In the field of power transmission, Beida Group is a professional manufacturer and supplier with over thirty years of experience, consistently driving development through technological innovation. As one of our core product lines, XLPE insulated PVC sheathed power cables have become the preferred solution for power engineering projects at voltage levels of 0.6/1kV and below, thanks to their reliable performance and wide applicability.
XLPE insulated PVC sheathed power cables utilize cross-linked polyethylene (XLPE) as the core insulation material. Through a physical cross-linking process, a three-dimensional network molecular structure is formed, significantly improving insulation performance and heat resistance.
The outer layer is covered with a polyvinyl chloride (PVC) sheath, forming a double protection system: the XLPE layer effectively prevents current leakage, while the PVC layer provides mechanical protection and resistance to environmental corrosion. This structural combination allows the cable to maintain stable operation under complex working conditions, reducing the failure rate by more than 40% over its lifespan.
This cable is designed for a voltage rating of 0.6/1kV, meeting the requirements of urban power grids, industrial distribution systems, and building electrical engineering applications. Its rated voltage parameters strictly adhere to the IEC 60502 standard, allowing it to withstand 1.2 times the overload voltage for continuous operation, and the insulation layer maintains its structural integrity during sudden short circuits.
Beida Group has optimized the ratio of conductor cross-sectional area to insulation thickness, increasing the long-term current carrying capacity of the cable by 15% at an ambient temperature of 35℃, effectively reducing line losses.
• Flame Retardant and Fire Resistant: It passes the GB/T 18380.3 standard test and can meet the Class A, Class B, and Class C combustion test requirements according to customer needs, thus meeting the fire protection requirements of densely populated places.
• Environmental Adaptability: The PVC sheath is modified with a special formula, improving UV aging resistance by 3 times. It maintains flexibility within a temperature range of -40℃ to +70℃ and can be directly buried or installed in conduits in humid environments.
• Mechanical Damage Resistance: The sheath surface hardness reaches Shore A 85 degrees, and it can withstand 20J of impact energy without rupture, making it suitable for complex construction sites such as building sites and mines.
• Cost-Effectiveness: Compared to rubber insulated cables, the cost per unit length is reduced by 25%, and the maintenance cycle is extended to 10 years, resulting in significant cost advantages over its entire lifecycle.
Beida Group's products have established a standardized supply system and are widely applied in the following areas:
Building power distribution: Used as main trunk cables in risers of residential buildings and commercial complexes, with single cables customizable up to 500 meters in length, reducing the number of intermediate joints.
Industrial energy: Providing power transmission for metallurgical workshops and chemical plants, resistant to corrosive media such as oil and acid mist.
Municipal engineering: Enabling rapid installation in urban street lighting systems and rail transit traction power supply through pre-branched structures.
New energy applications: Compatible with photovoltaic inverters and wind power converters, adapting to alternating environments of -40℃ extreme cold and +85℃ high temperature.
Renovation projects: In the upgrading of aging power grids, its outer diameter is 12% smaller than traditional cables, facilitating installation in narrow conduits.
As a national high-tech enterprise, Beida Group has established a comprehensive quality control system:
Raw Material Traceability: XLPE insulation material is made of cross-linked polyethylene, and the PVC sheath material is RoHS environmentally certified.
Production Monitoring: Online testing points are set up for multiple key processes to ensure that the insulation thickness and thermal elongation tests are qualified, and to ensure that the cable structure dimensions meet the standard requirements.
Factory Inspection: Each batch of products undergoes a 100% high-voltage test (3.5kV/5min, no breakdown).
From its modern production base in Beichen, Tianjin, to 32 warehousing and logistics centers nationwide, Beida Group, with our XLPE insulated PVC sheathed power cables, continuously provides reliable support for power infrastructure construction.
