Detailed Product Description

1-35KV Heat shrinkable power cable accessories

NSY,WSY,JSY,heat shrinkable power cable accessories have the advantages of light weight, reliable operation, convenient installation method, and inexpensive price,etc.

The products are suitable for terminal connection and intermediate-connection for cross-linking and oil-immersed power cable of 35KV and below -50^oC ~ +105^oC for a long time.

In addition, these accessories have been widely applied to the fields of power, petroleum and chemical industry, metallurgy, railway, port and building.

Basic performance of heat shrinkable material:

Service condition: It can be used under the condition of -50^oC~+100^oC for a long time

Aging lifetime: 20 years

Shrinkage rate: Radial direction≥50%, Longitudinal direction≤5%        

Temperature: 110^oC~140^oC

Whether the cable accessories can be operated reliably is decided by whether the electric field stress of the cut-off part of the cable shield can be controlled effectively.

The material of the heat shrinkage stress control pipe is provided with matching resistivity and dielectric constant. It shaped a certain characteristics at the end of the cable shield.

The impedance takes the effect of electrical stress control to absolutely guarantee reliable operation and the service lifetime of the accessories.

The electrical connection between the stress pipe and lead sheath of the oil-immersed cable can be solved by the one-core finger-cot.
