Transitioning To Heat Shrink Electrical Accessories from Conventional Insulating Practices

heat shrink

Are you still using conventional practice of insulating cables and other accessories to safeguard electrical installations against environmental impacts, usage errors, and risks? If you are experiencing increasing downtime because of frequent electrical faults causing financial losses in parallel, it is time to transit from conventional insulating practices to the advanced insulation practices. Yes, I am talking about heat shrink electrical accessories available for a range of applications to insulate power cables joints, cable terminations, switchgears, busbars, overhead lines, wooden poles etc.

Transitioning To Heat Shrink Electrical Accessories Is Easy

The ease of adoption, cost-effectiveness, required skills, and feasibility are the top concerns whenever you adopt a new technology. The leading manufacturers of heat shrink power cable accessories and other application-ready heat shrink products offer an ever-expanding product-line the suit your particular insulating needs. Each category of heat shrink insulation accessories has a range of low-cost products that do not need extra funds. In long run, you get the satisfactory ROI for spending heat shrink accessories. Adoption of heat shrink technology is easy because it does not need specific training. All the products come with usual manual to guide your existing electrical technicians.

Is It Reliable To Use Heat Shrink Accessories For Electrical Insulation?

Heat shrink tubing market is growing at a CAGR of 5.7% and it is expected to reach USD 2,730.98 million by 2028. The universal use of heat shrink insulation products is in challenging locations; may it be at indoor, outdoor , underground, under water, and ducts. If remote locations, design constraints, and harsh environments are your concerns, using heat shrink insulating accessories is the best solution. Made of cross-linked polyolefin, heat shrink electrical insulation products are – chemical resistant, UV resistant, waterproof, abrasion resistant, and flame retardant. Rust protection advantage is an extra reason that favors for using heat shrink products.

Heat Shrink Insulation Accessories Vs Conventional Insulating Tape

Electrical tapes generally made of vinyl, rubber, mastic, etc. is easier to apply. Heat shrink sleeves and other accessories come in predetermined shrink ratios that assure a more precise fit even to congested areas. With adhesive-lined heat shrink tubes, you can form waterproof seals. Heat shrink tubing creates a strong protection layer against the possibilities of physical damage.

The main limitation of electrical tape is its limited durability because over the period, it loses its adhesiveness to insulate the electrical cable or other components of electrical installation. When exposed to heat, conventional insulating tape starts deteriorating and harsh environmental factors accelerate deterioration process. Electrical tapes do not perform well in applications having exposure to chemicals and abrasion.

Five Tips to Take the First Step towards Heat Shrink Technology Adoption

With increasing adoption rate of heat shrink technology for insulating electrical accessories not only in industrial installations but in products also, the top manufacturers of heat shrink tubes, cable splicing kit, heat shrink tape, heat shrink couplers, protection shrouds, cable end sealing Caps, etc. provide application-ready insulating solutions. The following five tips will help you switch to heat shrink electrical accessories from conventional insulating tape-

  • Determine the accurate size/rating of cables and other accessories
  • Decide the spots in electrical installation that you want to insulate with heat shrink accessories
  • Deal with the top manufacturers of heat shrink electrical insulation accessories
  • Explore the entire product-line in a particular segment to select the best suitable accessories
  • Go through user manual to leverage the benefits of using heat shrink technology

How to Select the Right Heat Shrink Tube for a Particular Wire Size

Heat Shrink Tube

Heat shrink tube, also known as heat shrink sleeve, is a specially manufactured polyolefin casing widely used to provide tough insulation and corrosion protection to electrical cables, solder joints, components in electrical installation and mechanical components like pipes. Heat-shrink tubes, a type of extruded plastic tubes, when heated to a certain degree of temperature for a recommended period, reduce their size to get fit to particular application.

Although heat-shrink tubes are being used since decades yet many electrical engineers and technicians are refrained from the time-tested benefits of using heat-shrink tubes to secure their electrical and mechanical installations. Despite knowing the convincing benefits of using heat-shrink tubes, the numbers of electrical engineers and technicians avoid these small cost heat-shrink tubes insulating accessories just because of not knowing the selection of right size of heat-shrink sleeve for a particular wire size. Here I detail the heat-shrink tube terminology and selection process to help you choose the accurate heat-shrink sleeve size for a particular wire size.

Terminology For Heat-Shrink Tube Selection

What Is The Shrinkage Ratio? Heat-shrink tubes are available in expanded size that shrink when

Heat Shrink

Inner Diameter: There are two inner diameters- ‘Inner Diameter’ at supply time and ‘Inner Diameter’ after shrink.

Recovered Wall Thickness: The wall thickness also changes at recovery after heating. You should focus on recovery stage wall thickness while considering the particular application and environment.

How To Choose The Perfect Size Of Heat-Shrink Tube

The top manufacturers and reputed brands like Gala Thermo offer a wide range of heat-shrink tubes to facilitate its clients. The size of the object to be insulated is the base to determine the inner diameter, length, and shrinkage ratio of heat-shrink tube. The other key aspects that you should explore while buying heat-shrink tubes first time are – tubing material, operating temperature, shrinkage temperature, features, suitability to environment.

The most preferred shrink ratio is 2:1 or 3:1. It means, heat-shrink tube is expended 2 or 3 times to its original size. If you expect more size variation of object to be insulated, you should prefer larger shrink ratio. Here, you should keep in mind that there may be 10% of longitudinal change also.

The wall thickness is mentioned in mm or inches. Tubing’s technical data gives you complete information about the wall thickness. The heat-shrink tubes are available in single, double and heavy wall structures. Medium and heavy wall heat-shrink tubes are suitable for the cables up to 36KV. The single or thin wall structured heat shrink sleeves are good up to 3.3 kV electrical cables and components.

If you are buying the heat-shrink tubes to be used in industrial environment, you should also focus on resistance to weathering, chemical, solvents, UV rays, fungus etc. The other prominent properties, important for informed decision making, are tensile strength (as per ASTM-D-638), ultimate elongation (as per ASTM-D-638), and water absorption (as per ASTM-D-570), etc.

Pro-Tip

To be sure of choosing the quality best heat-shrink tube for the particular cable wire or component, you should also focus on quality standards. The top heat-shrink tube manufacturers and suppliers confirm the quality standards as RoHS Compliance, IEC 60684-3-247, IP 68, etc.
