WDMKYJYP fire-resistant and flame-retardant cable, low smoke and halogen-free cable for mining use

Mining halogen-free low smoke cable is a special cable designed specifically for mining environments, with characteristics such as halogen-free, low smoke, and flame retardant. It is widely used in underground mining sites such as coal mines and metal mines. With the continuous improvement of national requirements for mine safety and the enhancement of environmental awareness, the market demand for such cables continues to grow, and technical standards are becoming increasingly strict. A comprehensive analysis will be conducted from the aspects of product characteristics, application scenarios, technical standards, market status, and future development trends.

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

M: Special for coal mines (must meet the safety requirements of MT 818-1999 for explosion prevention, moisture prevention, etc.).

KYJYP：

KY: Control cable;

JY: Cross linked polyethylene insulation (XLPE);

P: Copper wire braided shielding (enhances electromagnetic interference resistance).

2、 Core Features

Conductor: oxygen free copper stranded (soft structure, multiple strands of fine copper wire), with stable conductivity.

Insulation and Sheath:

The insulation layer is made of cross-linked polyethylene (XLPE), with a temperature resistance of -40 ℃~90 ℃;

The sheath is made of low smoke halogen-free polyolefin (flame retardant Class B), which is environmentally friendly and flame retardant.

Shielding structure: Copper wire braided shielding (P), suitable for high interference environments.

3、 Technical parameters

Voltage level: 450/750V (low voltage control circuit).

Core count and cross-sectional area: Common specifications include 3 × 1.5, 12 × 1.5, 19 × 1.5, etc., supporting multi-core complex signal transmission.

Bending radius: ≥ 6 times the outer diameter of the cable, convenient for laying in narrow underground spaces.

4、 Application scenarios

Underground coal mines: used for monitoring systems, automation control equipment, and distribution lines.

Other fields: tunnels, subways, nuclear power plants and other places that require flame retardancy, low smoke and halogen-free.

5、 Comparison of derivative models

Model suffix meaning applicable scenarios

P2 copper strip shielding (non-woven) with higher shielding requirements in the environment

23 steel tape armor+copper tape shielding for high mechanical stress or strong interference areas

33 steel wire armored vertical shafts, inclined shafts and other tensile scenarios

Note: The specific selection should be based on the installation environment (such as whether armor is required) and signal transmission requirements.
