11KV 120mm2 Spaced Aerial Cable(SAC) Single-Core Aluminium Conductor XLPE Insulated HDPE Sheath
11KV 120mm2 Spaced Aerial Cable(SAC) Single-Core Aluminium Conductor XLPE Insulated HDPE Sheath
Description
XLPE insulated or covered aerial cable without or with conductor screen, the phase conductor may be AAC or AAAC or ACSR or Copper.
Construction
1. Conductor : Compact round stranded hard-drawn
2. Conductor screen: Semi conductive cross-linked polyethylene (XLPE) compound
3. Insulation : Cross-linked polyethylene (XLPE)
4. Jacket : Black cross-linked polyethylene (XLPE) or HDPE
Operating Characteristics
Operating voltage: 10kV 15kv 24kv 25kv 35kv
Max. permissible continuous operating temperature of conductor with XLPE insulation: 90°C
Max. temperature of conductor during short-circuit (5s max. duration) shall not exceed: 250°C
The ambient temperature under installation should not be lower than: -20°C
The bending radius of cable is recommended as following:
Single core cable: not less than 20 times of the diameter of cable
Multi-core cable: not less than 15 times of the diameter of cable
Application
XLPE insulated aerial cable as a new-type aerial cable is used for overhead electric power transmission and distribution, extensively used in rebuilding of urban and forest region electrified wire netting. It improves the safety and reliance of electrified wire netting.
