WDMYJY mining cable 23 steel belt armor 33 steel wire armor

The main difference between WD-MYJY23 and WD-MYJY33 cables lies in their armor structure and applicable environment.

The specific comparison is as follows:

1. Differences in Armor Structure

WD-MYJY23: Adopting double steel strip wrapped armor (in the number "23", "2" represents steel strip armor, and "3" represents polyethylene sheath). This structure provides strong radial compression resistance and is suitable for situations that require prevention of mechanical compression and rodent bites.

WD-MYJY33: Adopting fine steel wire armor (in the number "33", "3" represents fine steel wire armor). Steel wire armor has higher tensile strength and is suitable for environments that require significant longitudinal tension or frequent movement, such as mine hoists and inclined shaft transportation equipment.

2. Differences in applicable scenarios

WD-MYJY23: Steel tape armor provides better radial pressure protection and is commonly used for fixed installation? Power supply for underground tunnels, tunnels, and other ground equipment, or fixed lines that require anti compression.

WD-MYJY33: Fine steel wire armor has strong tensile performance and is more suitable for dynamic laying or scenarios that require tension, such as underground mobile equipment, coal mining machine dragging cables, etc.

3. 共同特性

Both have the following core characteristics:

Zero halogen and low smoke: There is no toxic halogen gas released during combustion, and the smoke transmittance is ≥ 60%, which meets the safety standards of coal mines.

Cross linked polyethylene insulation: high temperature resistance, aging resistance, and stable electrical performance.

Polyolefin sheath: corrosion-resistant, waterproof, suitable for humid environments.

summary

When choosing, it is necessary to consider the actual needs:

If compression resistance and mechanical damage prevention are required, choose WD-MYJY23 (steel belt armor).

If tensile strength and adaptability to dynamic environments are required, choose WD-MYJY33 (fine steel wire armor).
