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

Cable jointing is an indispensable exercise for electrical engineers. High expectations are placed on this skill because a cable joint protects cables against dust, moisture ingress, and penetration impact of foreign objects. A range of cable jointing systems and termination kits is available to facilitate engineers to distribute and supply electricity securely at medium/high voltages in transformer terminals, switchgear, air-insulated cable boxes, poles, etc. The emergence of heat shrink technology and time-tested beneficial results strengthen the confidence of end users to use this technology for better security measures to protect their electrical installations. The increasing use of heat-shrink cable joints, heat shrink cable sleeves, and other accessories is the result of expanding range of the product line in each category.

Emergence of Heat Shrink Cable Joints as the Robust Insulation Measure

Cable joints play a key role in the performance of electrical installations and electronic systems. These are used to connect power cables ensuring the continuity of electric current. Different types of heat shrink cable joints are used in industrial and large commercial electrical installations; the selection depends upon the intended application and on-site condition. Similarly, heat shrinkable terminations are made available by the leading manufacturers of heat shrink electrical insulation accessories to facilitate engineers for terminating the power cables securely. Heat shrink accessories shrink to their original size when exposed to heat with an electric or gas heat gun; the phenomenon simplifies the power cable insulation task for engineers. https://www.youtube.com/watch?v=2h41GJ_jH20
