WD-MKYJYRP 450/750V 4 * 1.0 Gold Mine Control Cable

WD-MKYJYRP is a halogen-free low smoke shielded control flexible cable designed specifically for mining environments. It has excellent flame retardancy, environmental protection, and safety performance, and is suitable for signal transmission in control systems under harsh working conditions such as mines. Its core features and technical parameters are as follows:

1、 Product Structure and Naming Analysis

Model definition:

WD: halogen-free low smoke (no toxic halogen gases during combustion, high smoke transmittance)

MK: Mining control cable

YJ: Cross linked polyethylene insulation (high temperature resistance, stable electrical performance)

Y: Polyolefin sheath (environmentally friendly and flame-retardant)

RP: Braided shielding+soft structure conductor (strong anti-interference ability, good flexibility)

2、 Core performance characteristics

Safety and Environmental Protection:

During combustion, no corrosive gases (such as chlorine gas) or toxic smoke are released, and the light transmittance is high, ensuring the escape visibility of underground personnel.

The material does not contain harmful heavy metals such as lead and cadmium, and meets environmental protection requirements

Protective features:

Shielding design: The woven metal shielding layer effectively suppresses electromagnetic interference and ensures signal transmission stability

Flame retardant and fire-resistant: According to the MT/T386-2011 mining standard, it has the ability of flame retardant and self extinguishing.

Mechanical properties:

The soft conductor structure enhances flexibility and adapts to complex wiring environments in mines.

The sheath is wear-resistant and corrosion-resistant, extending its service life

4、 Typical application scenarios

Mining equipment: signal control circuits for underground lifting systems, ventilation equipment, and monitoring devices.

High risk areas: high-rise buildings, subway tunnels, petrochemicals, and other areas that require a high level of fire safety.

5、 Precautions for use

When laying, the minimum bending radius (≥ 10 times the cable diameter) should be maintained to avoid excessive bending and damage to the wire core.

Regularly check the integrity of the protective sheath, replace aging cables in a timely manner, and ensure system reliability
