Indoor Cable Heat Shrinkable Kit

1kV 10kV 35kV Indoor cable heat shrinkable kit termination refers to a complete cable termination assembly formed by using various components made of heat-shrinkable materials (such as radiation-cross-linked polyolefin), like tubes, branch-offs, and sheds.

These components are heated and shrunk to tightly wrap around the cable end and its connection point (e.g., to a switch or transformer terminal). This process restores insulation, provides sealing, offers mechanical protection, and improves electric field distribution.

 

Model meaning example:

1. WSY-10/1.3 is10kV cross-linked polyethylene outdoor heat shrink terminal, it is suitable for 1-core cables with cross-section 150-240mm².
2. NSY-20/2.3 is 20kV cross-linked polyethylene Indoor cable heat shrinkable kit, it is suitable for 2-core cable with cross-section 300-400mm².

3. JSY-1/3.2 is 1kV cross-linked polyethylene heat shrink cable center coupling, it is suitable for 3-core cable with cross-section 70-120mm².

 

 

1KV, 10kv,20kV, 35kV heat shrink power cable terminal, intermediate connector series products, it integrates waterproof, stress control, shielding and insulation,and has good electrical and mechanical properties and can be used for a long time under various harsh environmental conditions.

Indoor cable heat shrinkable kit is widely used in electric power, petrochemical industry, metallurgy, railway port and construction field.

 

 

 

● Stress Control Tube/Tape/Gel：It is used to dissipate the concentrated electrical stress at the cut-off point of the cable shield

● Heat-Shrink Insulation Tube：It is the core component ensuring electrical safety.

● Heat-Shrink Seal Tube：Used for the outermost sealing of the termination, preventing moisture ingress, and also for filling voids between cable cores.

● Heat-Shrink Breakout：Used for multi-core cables (e.g., three-core cables) to separate the individual cores and provide sealing for the cable body.

● Lug/Terminal：Crimped onto the cable conductor for connecting to the terminal stud of switchgear or transformers.

● Phase Identification Tube：Sleeved over each phase's insulation tube to identify phases A (Yellow), B (Green), and C (Red) for easy recognition.

 

 

 

Vulnerability: Cable accessories are the weakest part; installation quality is crucial for safety.

Qualified Personnel: Only specially trained personnel should perform the installation.

Instruction Manual: Read and follow the manual carefully.

Power Off Devices: Ensure all devices and cables are powered off before starting.

Cable Condition: Check that cables are intact and dry; avoid damp cables.

Specification Check: Verify that accessory specifications match the cables and check component completeness.

Weather Conditions: Avoid installation in rain, fog, or wind; use heating measures if below 5°C.

Cleanliness: Keep hands, tools, and materials clean; avoid unrelated activities during installation.

Normal Phenomenon: Red glue flowing from the cold shrinkable sleeve after heating is normal.
