XLPE/PVC POWER CABLES

Power cables are designed for permanent use and may be installed as overhead wiring, exposed wiring, and direct burial applications. The power cable is constructed of one or more electrical conductors with a covering and is available in various constructions, materials, and ratings for different applications.

Power cables are commonly used in the electric industrial and commercial markets. You can find power cables in power supply systems, motor leads, signal systems, etc.

A portable cord is designed for temporary power supply, while power cables are usually installed in permanent applications.

Copper class 5 (flexible) power cable: This type of cable is suitable for electrical power transmission in all types of low voltage industrial-type connections, in urban grids, building installations, etc. Power cables are made of a copper conductor, a protective insulation and an outer sheath. These cables can be easily bent and routed, making it suitable for use in tight spaces. They can be buried or installed in a tube as well as outdoors without requiring additional protection.

XLPE stands for Cross-Linked Polyethylene. It is a type of insulation material used in electrical cables. The “cross-linked” process involves chemically bonding the polyethylene molecules, which enhances the material’s properties . The way in which this cable is usually made is by joining the molecules in strands to obtain the well-known cable insulation.

The most important features of XLPE cables are:
• Light weight
• High heat resistance
• High load capacity
• Corrosion resistant
• Does not melt easily
• Higher tensile strength
• Longer service life
• Better impact resistance
• Higher tensile strength
• Excellent electrical properties

Both PVC (Polyvinyl Chloride) and XLPE (Cross-Linked Polyethylene) have their own advantages, and the choice between them often depends on the specific application and requirements.

PVC is generally more flexible and easier to work with, making it a popular choice for many standard insulation applications. It also has good resistance to moisture and chemicals, which can be beneficial in various environments.

XLPE, on the other hand, offers superior thermal and electrical properties. It has a higher temperature rating and better resistance to heat, making it ideal for applications that involve higher temperatures or require better performance under stress. XLPE is also more resistant to environmental factors like UV radiation and has a longer lifespan.

PVC stands for Polyvinyl Chloride. It is a type of plastic commonly used as an insulation material for electrical wiring. PVC is favored for its durability, flexibility, and resistance to moisture, chemicals, and abrasion. It helps protect the conductors inside the cable from environmental factors and ensures safe electrical performance. Additionally, PVC is relatively cost-effective, making it a popular choice in various electrical applications.

XLPE cables, or cross-linked polyethylene cables, are best suited for a variety of applications due to their excellent thermal, electrical, and mechanical properties. Can be used to power distribution, industrial applications, renewable energy and marine cables.

XLPE cables generally have a higher temperature rating compared to PVC cables. Specifically, XLPE (cross-linked polyethylene) cables can typically handle temperatures up to around 90°C for continuous operation, and even higher for short periods. In contrast, PVC (polyvinyl chloride) cables usually have a maximum temperature rating of about 70°C for continuous use.

Yes, XLPE cables are generally more expensive than PVC cables. The higher cost of XLPE cables is due to the more complex manufacturing process and the superior materials used, which provide better thermal and electrical performance. Additionally, XLPE cables offer advantages like higher temperature ratings, better resistance to environmental factors, and longer lifespan, which can justify the higher initial investment in many applications.
