Heat shrink technology is gaining wider scale popularity in almost all business sectors including manufacturing, construction, processing, and others. People are getting more aware of the security measures that they should apply to their electrical installations. The industrial engineers and engineering consultants are recommending the use of heat shrink cable accessories to make the people and the premises safe against any possible hazard often triggered by poor insulation, loose connection, and degraded cable.

Time Tested Heat Shrink Technology: The heat shrink technology was introduced around 62 yrs back. Over the decades, the heat shrink accessories industry has become a global enterprise of billions of dollars (US) worth today. The technology is based on specially-formulated thermoplastic polymer materials like polyolefin, fluoropolymer, PVC, silicone elastomer, neoprene, Viton, etc that display shape memory. The increasing use of heat shrink cable accessories opened some avenues of discovery pertaining to material behavior and radiation effects. So far, the results have been largely favorable.

Heat Shrink Sleeves- Protection Against Harsh Environment: The lion share of the heat shrink tubing market is of electrical insulation. Heat shrink sleeves not only protect or secure the wiring connectors and splicing but also provide insulation. When regulatory provisions are met in applications of heat shrink cable accessories, the technology gives dependable protection against environmental impacts, behavioral impacts, and aging impacts. The elements like chemical environment and temperature are important to consider while using heat shrink electrical insulation accessories but there are many others also like abrasion, scraping, rough handling, vibration, etc.

How Easy Is It To Use Heat Shrink Electrical Accessories: Ok, it may be your first time to considering heat shrink technology to secure your electrical installations to reduce the possibility of accidents, and number of breakdowns because of flashover, and maintenance costs. The leading manufacturers and suppliers of heat shrink accessories provide online assistance at no cost. The use of heat shrink tubes in any environment is easy. Just place it around the joint of cables and heat it with a heat gun as per directions for the recommended period and leave it; your task of cable insulation is complete.

How Reliable Are Heat Shrink Insulation Accessories?

• Shrink ratio: 2:1 and 3:1
• IEC 60684-3-247 standard and IP 68 norms
• Excellent resistance to weather impacts, UV rays, and chemicals
• Suitable for indoor, outdoor, and underground usage environment
• Continuous-use temperatures from -55 to 135 °C
• Test standards DIN EN 50393
• Tensile strength9 N/mm2
• Dielectric strength>15kV / mm

The increasing numbers of engineers and consultants have accepted the effectiveness of heat shrink technology to secure electrical installations; they are in favor of embracing heat shrink tubes at least in middle to large electrical installations. When the manufacturers of heat shrink sleeves are expanding their product line to facilitate the users, the first time users still have some clouds over their inclination towards using heat shrink tubes or sleeves. The success of getting the ultimate results as you expect by using the most advanced electrical insulation technology depends upon choosing the right shrink ratio, diameter, & length of heat shrink tubes or sleeves.

Shrink Ratio of Heat Shrink Tubes: Heat shrink tubes are manufactured to give 2:1 or 3:1 shrink ratios. It means the heat shrink tube expands two or three times on being heated. When the tubes are shrunk, it is considered in the recovered state. The 2:1 shrink ratio of heat shrink tubes is good for jacketing wire bundles or harnesses. The 3:1 ratio is good to seal irregular shapes. Both the heat shrink tubes of2:1 and 3:1 shrink ratios are available in single wall tubing and dual wall tubing structures.

Diameter of Heat Shrink Sleeves: The ideal recovered diameter of the underlying cables should be measured at the widest part. The ideal heat shrink tubes would be of 20% – 30% larger diameter. The internal and outer diameters are listed in the data sheets; you should focus more on the internal diameter of heat shrink tubes to get the best fit insulation solution.

Length of Heat Shrink Tubes: The length of heat shrink tubes is associated with longitudinal shrinkage. Heat shrinkable sleeves shrink in length also during the recovery process. Focus on the change in length after recovery stage. Longitudinal shrinkage in heat shrink sleeves varies from 5% to 10%; and, it depends upon the tube material.

Which heat shrink tubing should you choose- Single Wall vs. Dual Wall Tubing:  The heat shrink tubes are being used to address multiple diverse concerns like strain relief, insulation, cosmetic, sealing, and protection. Dual wall shrink tubes work for all of these concerns but using these cables everywhere while neglecting the suitability of single wall shrink tubes may be overkill because of cost factors.

Most single-wall heat shrink tubes are made of polyolefin; this cross-linked material has a shrink temperature of 100°C and can withstand temperatures up to 125°C-135°C. The most common shrink ratio for polyolefin single wall heat shrink tubes is 2:1 but these are made available in 3:1 and 4:1 ratios also if a customer demands. Dual wall heat shrink tubes are used to get protection against the continuous presence of moisture. Dual wall heat shrink sleeves provide extra sealing to prevent chemicals, fluids, and water to erode your connections. Dual wall tubes are made of two different layers- the outer layer is of cross-linked polyolefin and the inside layer is of an adhesive that melts on being heated.

Pro-tip: When you decide to use heat shrink tubes to insulate and secure your electrical installations in the best possible way, also use other heat shrink insulation accessories to insulate poles, switchgear, busbars, etc.

Cold shrink and heat shrink tubes look identical when you see them at the surface but the internal characteristics are too different. Cold shrink and heat shrink tubes have different insulation mechanisms because of different properties; therefore, these are used in different applications. The tubing is used in an increasing range of applications in different business sectors; the usage is not limited just to insulation, splicing, environmental sealing, terminating, etc. Heat shrink and cold shrink tubes and accessories are more cost-effective to be used in harsh environments than using other tubing types. A thin separation line exists between heat shrink and cold shrink tubes; the major difference we see in the way of application of both.

Heat shrink tubes come pre-stretched. Heat shrink tubes need a heat source for tight-fit installation and can’t be installed without a heat gun. On being heated, the polyolefin heat shrink cable tubing shrinks to its original size to create a tight-fit seal on the cable joint. The polyolefin material used in heat shrink tubes is highly resistant to chemicals, gases, and water because it becomes extremely ridged after heating. Heat shrink tubes are preferred because of getting mechanical protection also. Heat shrinks tubes are finding increasing applications in industrial and commercial installations in low-temperature areas where the presence of chemical gases is high in the environment. The prominent heat shrink tubes manufacturers supply and export different types of heat shrink tubes made of-

• Polyolefin
• PTFE (Polytetrafluoroethylene)
• FEP (Fluorinated ethylene propylene)
• PVDF (Polyvinylidene fluoride)
• Elastomeric
• Silicone

Cold shrink tubes are made of silicone rubber. These are made available in stretched form with a removable plastic core that facilitates for easy mobility. After the placement of cold shrink tubes over the cable joints or cable terminations, the inner cover is pulled out allowing the tube to contract up to its pre-stretched size and to deliver a long-term effective sealing of the joint. Cold shrink tubes are a better option to protect XLPE cable insulation against overheating. Cold shrink tubes also benefit the users because you don’t need an ideal time for cooling before energizing the cables. Cold shrink tubes create a static and stable seal over the joints that don’t expand or contract. Typical applications of cold shrink tubes include – Sub-Bottom Profiling, Sidescan Sonars, underwater camera systems, data telemetry systems, digital video recorders, electric survey winches, marine pumps, underwater trenching machines, etc.

Is it good to invest in installing heat shrink electrical accessories? Why are more and more numbers of manufacturing units and commercial businesses embracing heat shrink technology? Why do more numbers of architects and industrial consultants recommend the use of heat shrink tubes and other heat shrink connectors to make electrical installations safe?

Why Using Heat Shrink Electrical Protection Is A Good Practice

Heat shrink technology creates a protective seal around the electrical wires or connections. Heat shrink electrical accessories are made from a substance that shrinks in diameter when heated; shrinkage creates a secure seal. Heat shrink electrical protection accessories are used not only to make electrical installations safer but for other purposes also like for-

• Creating cable entry seals for environmental protection
• Bundling multiple wires together
• Replacing worn insulation on wires
• Protecting underground electrical lines from corrosion
• Reducing mechanical and die-electric stresses
• Making the electrical installations more professional looking

Parameters for Using Heat Shrink Tubes and Accessories

Most of the heat shrink electrical protection accessories are made of Polyolefin, a resin that has excellent resistance to corrosion, moisture, UV rays, and chemicals. The shrink ratio is a major aspect to be considered; it is the ratios to compare the original heat shrink tube size to its shrunken size. The more common shrink rations are 2:1 to 4:1. Also, there are two types of heat shrink accessories – single wall and dual-wall heat shrink accessories. The commonly recommended shrink temperature for most polyolefin materials is around 90°C. An easily available heat gun is used to heat and shrink the heat-shrink insulation products. You should never open flame sources. The focused heat by open flame may melt the sleeves, create uneven shrinkage, or create over-shrinkage.

Easy To Apply Heat Shrink Electrical Protection Accessories

The top manufacturers of heat shrink heat shrink electrical protection products facilitate the engineers and on-site technicians to seal the electrical connection according to international standards that too at a very nominal cost. For example, Gala Thermo, a prominent manufacturer, supplier, and exporter of heat shrink electrical insulation accessories, offers different products in each category created to suit on-site requirements- Heat-shrinkable joints & terminations; screened separable connectors; heat shrinkable moulded shapes; heat shrink sleeves; switchgear insulation products; cable sealing products; overhead line cover; pole protection caps; etc.

Always buy heat shrink tubes with a smaller after-shrink inner diameter than the diameter of the cable to be insulated. For example, a heat shrink sleeve with an after-shrink diameter of 10 millimeters wouldn’t serve the purpose on a cable with a diameter of 9 millimeters. The piece of heat shrink tubing should be more than the cable length to be insulated to adjust the longitudinal shrinkage that is about 1% – 8% of the length.

A little investment in using heat shrink electrical protection accessories saves your spaces from fire and on-site accidents that total disturb your progress. Invest little in heat shrink accessories to safeguard self, your employees, your assets, and your social repute.

When used as an electrical insulation cover, heat shrink sleeves provide dependable protection against abrasion, scuffing, cutting, and impacts. These can be used to insulate virtually any type of electrical conductor. Heat shrink tubes are also being used to create secure cable entry seals with adequate protection from the surrounding threats and adverse environmental conditions. Before you take initiative to buy heat shrink sleeves, it is a must to be sure of their effectiveness, benefits, capabilities, and the most accurate size.
