In the ever-evolving world of electrical installations, ensuring the reliability and durability of connections is paramount. Heat shrink power cable accessories have emerged as an essential component for any professional looking to enhance their electrical solutions. Heat shrink power cable accessories are specialized products designed to provide insulation, protection, and strain relief to electrical connections. Made from polymer materials that shrink upon heating, these accessories tightly conform to the cables, ensuring a secure fit around joints, terminations, and splices. They come in various forms. In this blog, we will explore the importance, usage, and benefits of using heat shrink end caps or cable end sealing caps.
Understanding Heat Shrink End Caps
These are widely used to protect and seal cables, wires, and pipes from environmental damage and electrical shocks. Also known as cable end sealing caps, heat shrink end caps are used across industries including automotive, industrial engineering, telecommunications, and energy. These are used to seal unused outlets also. Heat shrink end caps have become an integral part of maintenance of telecommunications cables, including pressurized and unpressurized cables. Because of being flame-retardant, temperature resistant, and water-proof, these small-coast power cable accessories offer excellent insulation. Hot melt heat shrink end caps are designed with 3:1 shrink ratio. The cable ends can be sealed ensuring high di-electric insulation and superior sealing properties. Hot shrink ends have an activation temperature of 120-135C. When heated at this temperature, the adhesive lining inside the cap melts down causing the outer jacket shrink while the inner wall melts and flows into the capped end. Lets explore the variety in heat shrink end caps-
- Heat shrink cable end sealing caps are highly useful to protect the cables in harsh conditions like those that you see in chemical and processing industries. Cable end sealing caps cover and protect the cable terminals and prevent corrosion and damage over the time. Elastomeric end seal is made from specially formulated rubber compound. These are designed to give optimum efficiency to the curing process by holding pressure to the desired level. Heat shrink moulded cable end sealing caps are compatible with most commonly used cable jackets i.e. XLPE, PVC, PILC or rubber sheathed cable.
- Insulcap is used seal the ends of all types of cables and protect from ingress of water / moisture. The caps are manufactured from high-quality cross-linked polyolefin material. Compatible with most commonly used cable jackets i.e. XLPE, PVC, PILC or rubber sheathed cable. Excellent resistance to weathering, moisture, contamination and adverse environmental conditions is ensured according to IP 68. Hot melt adhesive lining provides permanent seal on irregular cable sheaths.
- Insulcap-Live (GLEC) are Heat Shrinkable Caps, used to seal the live cables. Each core is separately sealed using small end caps. Finally, a thick wall outer heat shrink cap is applied marked with a live flash symbol.
- Insulcap-De-gassing (RV) is heat shrinkable end caps, supplied with Relief Valve (RV) and are used for sealing high voltage and extra high voltage cables (33 kV & above) to release the constantly evolving gas generated inside the cable during transportation & storage in hot climate conditions.
