The importance of electrical protection in industrial and commercial spaces is increasing in parallel to our increasing reliance on electrical machinery. The increasing numbers of fire incidents and fatal injuries in India because of poor standards of electrical safety measures denote that it is a commonly neglected area despite no shortage of funds. Heat shrink electrical protection products offer an affordable solution to avoid possibilities of short-circuits, shocks, fire-broke out, improper power supply to 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.
