Product Introduction
Product application:
as the name suggests, mining cable refers to the wire and cable used in mining industry. Mining cable will be used to connect shearer, conveyor and basic lighting communication equipment in coal mining industry. When mining cables are used in underground operation, jumper cables are usually used for high-voltage power supply lines. The weakest link in mining cable power supply is mining area power supply, and it is also in a place with bad environment. Therefore, when selecting mining cables, pay attention to the cross-sectional area of cable model and its safety, so as to ensure safety
