10kV heat-shrinkable termination
Model:
1 / 2

Description
1. Double ground wire process for heat-shrinkable termination heads of cross-linked cables. That is, the steel armor ground wire and the copper shield ground wire are separated, making cable preventive testing more reasonable. a. Measure the steel armor ground wire-to-ground resistance; if conductive, the inner lining layer has been damaged. Measure the copper shield ground wire-to-ground resistance; if conductive, both the inner and outer jackets of the cable have been damaged. c. A triangular cushion cone was developed for construction convenience. d. The finger shank has a tapered structure and never cracks.
Features
- 1. Double ground wire technique for heat-shrinkable terminal head of cross-linked cable. That is, the steel armor ground wire and the copper shield ground wire are separated, making cable pre-testing more reasonable. a. Measure the resistance between the steel armor ground wire and ground; continuity indicates that the inner lining layer has been damaged. Measure the resistance between the copper shield ground wire and ground; continuity indicates that both the inner and outer protective layers of the cable have been damaged. c. A triangular cushion cone was developed for construction convenience. d. The finger sleeve has a tapered structure and never cracks.
