Mining copper core power cable MVV-0.6/1KV 4 * 1.5

Mining copper core power cable MVV-0.6/1KV 4 * 1.5

MVV cable

Structure: Copper conductor+polyvinyl chloride (PVC) insulation layer+PVC sheath, without armor layer

Features:

Wear resistance, anti-aging, suitable for wet and dusty mine environment

Unable to withstand mechanical external forces, only suitable for fixed installation scenarios without compression risk

Long term working temperature ≤ 65 ℃, laying environment temperature ≥ 0 ℃

MVV22 cable

Structure: Adding double-layer steel strip armor on the basis of MVV, with an outer layer covered with PVC sheath

Features:

Steel belt armor provides compressive and impact resistance, and can withstand rock compression and mechanical collisions

Suitable for underground environments with external force risks (such as mobile equipment power supply, complex geological areas)

Flame retardant design reduces the risk of fire spread.

3、 Technical parameters

Rated voltage: 0.6/1kV (both applicable).

Conductor cross-section: 1.5mm ² to 300mm ² (MVV22 can reach 185mm ² with a dual core design of 10).

Protection level: Complies with coal mine safety standards (such as MT818-1999).

4、 Key factors for selection

Mechanical protection requirement: MVV22 must be selected when there is a risk of compression or impact.

Laying method: Fixed overhead/conduit optional MVV; Choose MVV22 for direct burial or complex tunnels.

Cost considerations: MVV costs less than MVV22 (due to lack of armor layer)

5、 Precautions

Cable integrity should be checked during installation to avoid use in flammable environments

The steel belt armor of MVV22 may increase weight, and the load-bearing capacity of the tunnel needs to be evaluated

Summary: MVV is suitable for low-risk fixed scenarios and has excellent economic efficiency; MVV22 enhances mechanical protection through armor design, making it a choice for high-risk areas
