Suitable for high-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, mines, petroleum, chemical industries, etc. It is difficult to catch fire and has the ability to prevent or spread. Moreover, once it catches fire, it has the characteristics of halogen-free, low smoke, harmless, and non corrosive.

Copper core cross-linked polyethylene insulated copper tape shielded halogen-free low smoke Class B flame-retardant control flexible cable

Low smoke halogen-free cables can be divided into low smoke halogen-free flame retardant series and low smoke halogen-free fire-resistant series.

Low smoke halogen-free cables are produced by our company in accordance with French standards RCCE and NF series standards, national standards GB/T18380, GB/T19216, GB/T17651, GB/T17650, and other standards.

WD-MKYJY23 450/750V3 * 2.5 Gold Mine Armored Control Cable

The WD-MKYJY series of halogen-free and low smoke control cables for mines are a special type of cable designed specifically for coal mines and similar high-risk environments. They have characteristics such as flame retardancy, low smoke, halogen-free, and corrosion resistance, and are widely used in places with high safety requirements such as mines, tunnels, and nuclear power plants. This series of cable models is diverse, with key features such as structure, shielding, armor, and flexibility distinguished by suffix letters and numbers to meet different operating conditions.

1、 Analysis of Naming Rules for Core Models

The WD-MKYJY series models consist of multiple letter combinations, each with a specific meaning:

WD: Halogen free low smoke (compliant with GB/T 19666-2019), no toxic halogen emissions during combustion, smoke transmittance ≥ 60%

M: Specially designed for coal mines, it must meet safety standards such as MT 818 explosion-proof and moisture-proof

KYJ: Control cable, cross-linked polyethylene (XLPE) insulation, excellent temperature resistance (-40 ℃~90 ℃)

Y: Polyolefin sheath, with flame-retardant Class B, low smoke and halogen-free characteristics

Subsequent letters represent structural variations:
