250 MCM 3C Stranded Bare Copper Tape Unshielded XLPE PVC RE4H1(O)R 8.7/15KV Medium Voltage Cable
Allowable Ampacity for 250 MCM 3C Stranded Bare Copper Tape Unshielded XLPE PVC RE4H1(O)R 8.7/15KV Medium Voltage Cable: 100 Amps
About:
This type of cable is engineered for medium voltage applications, capable of supporting voltage levels of 8.7/15 kV. It features a three-conductor design with stranded bare copper to enhance flexibility and conductivity. The cable uses cross-linked polyethylene (XLPE) for insulation, which is known for its high electrical insulation properties and resistance to various environmental factors. The outer jacket is made of PVC, providing a robust layer of protection against physical and chemical stressors.
Also Known As:
The naming conventions for such cables can vary between manufacturers and regions, but the key specifications (250 MCMAWG 3C, Stranded Bare Copper, XLPE PVC, 8.7/15KV) typically remain consistent. This cable might also be referred to based on its specific application or construction nuances, although the base identifier would likely remain recognizable across different contexts.
