Frequently Asked Questions (FAQ) – Medium Voltage Cables

What defines a medium voltage cable?

Medium voltage cables are designed for power distribution systems, capable of handling voltages typically between 1 kV and 69 kV. These cables are essential in industrial, utility, and commercial installations.

What are the main characteristics of MV cables?

MV cables are constructed with robust materials and engineered for reliability. They typically feature high-quality insulation, durable conductors, and are tested for electrical, thermal, and mechanical performance.

How do I choose the right MV cable for my needs?

Selecting the right MV cable involves evaluating:

• Voltage requirements

• Installation environment and ambient temperature

• Cable run length

• Insulation and conductor materials
  Our technical team can assist in identifying the best solution for your specific application.

What materials are used for MV cable conductors?

MV cable conductors are usually made of copper or aluminum. Copper offers superior conductivity, while aluminum is valued for its light weight and cost-effectiveness.

Which insulation materials are commonly used?

The most widely used insulation materials include:

• XLPE (Cross-linked Polyethylene)

• EPR (Ethylene Propylene Rubber)

• PVC (Polyvinyl Chloride)
  These materials are chosen based on performance, flexibility, and environmental compatibility.

Are Life Cable MV cables fire-retardant?

Yes. Many of our MV cables are fire-retardant, halogen-free, and designed to meet international fire safety standards. For example, our X-VOLT® AL RHZ1 (AS) cable complies with:

• EN 50399 (fire propagation)

• IEC 60332-1 (flame propagation)

• EN 60754-1/-2 (low emission of corrosive gases)

• EN 61034 / IEC 61034 (low smoke density)
  It is CPR rated Cca-s1b, d2, a1, ensuring top-tier fire safety.

How are MV cables tested for quality and reliability?

MV cables undergo extensive factory testing, including:

• Electrical: dielectric strength, partial discharge, insulation resistance

• Mechanical: tensile strength, flexibility, elongation

• Thermal: aging tests to simulate long-term use
  These tests confirm the durability, safety, and efficiency of our cables.

What standards must MV cables meet?

Our MV cables are designed in compliance with IEC 60502-2, ensuring reliability and performance in power generation, distribution, and select transmission systems.

How often should MV cables be maintained?

Routine inspections are essential. Follow a preventive maintenance schedule to monitor for signs of wear or damage, based on manufacturer recommendations and industry standards.

What are the safety concerns with MV cables?

Potential hazards include:

• Electric shock

• Arc flash

• Fire risk
  Proper installation, regular inspections, and use of PPE help mitigate these risks.

Where are medium voltage cables commonly used?

MV cables are ideal for:

• Power distribution systems

• Industrial plants

• Renewable energy projects

• Data centers

Are MV cables suitable for underground use?

Yes, MV cables are widely used in underground installations for added protection and reduced outage risks. Proper trenching, insulation, soil condition assessment, and protection layers ensure long-term performance.

What is a utility cable?

A utility cable is a type of MV cable used in electrical grid infrastructure, transferring power from generation sources to commercial, residential, and industrial users.

Which MV cables are best for industrial plants?

Industrial facilities require MV cables that can power heavy equipment and withstand harsh environments. Life Cable’s industrial-grade MV cables are engineered to resist:

• Oil and chemical exposure

• High temperatures

• Mechanical stress

What about MV cables for renewable energy?

MV cables used in solar and wind energy systems are designed to handle variable voltages, harsh weather, UV exposure, and long-distance transmission with high efficiency and minimal losses.

How are MV cables used in transport infrastructure?

MV cables are essential in powering:

• Electric railways

• Subway systems

• Airports
  These installations require cables that are flame-retardant, low smoke, and abrasion-resistant to meet strict safety regulations.

Are MV cables chemically resistant?

Yes, our MV cables are made with materials selected for high chemical resistance, protecting them from hydrocarbons, solvents, and corrosive agents commonly found in industrial environments.
