Rated Voltage 10kV & 35kV Insulated Aerial Cable
Uses:
The product is suitable to be used for power distribution and supply of electric transmission aerial line with power frequency rated voltage 10kV and 35kv. And the allowable long-term working temperature of cable conductor can be above:
High-density polyethylene insulated aerial cable: 75 0 C;
Cross-linked polyethylene insulated aerial cable: 90 0 C;
When short circuit occurs, (the longest sustained time not over 5 seconds) the highest temperature of cable conductor shouldn't be above:
High-density polyethylene insulated aerial cable: 150 0 C;
Cross-linked polyethylene insulated aerial cable: 250 0 C.
