Title:
B1-LEVEL 35KV LOOPED NETWORK CABLE FOR URBAN RAIL TRANSIT TRACTION POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/036888
Kind Code:
A1
Abstract:
A B1-level 35kV looped network cable for an urban rail transit traction power supply system, relating to the field of power supply circuits. The B1-level 35kV looped network cable for the urban rail transit traction power supply system comprises a cable core assembly (100), and a high-flame-retardant fireproof layer (210) and a copper-zinc alloy layer (220) that cover the cable core assembly (100). According to the B1-level 35kV looped network cable for the urban rail transit traction power supply system can solve the problem of heat release during cable combustion and improve the rat bite prevention capacity.
