What Are High Voltage Cables?

Introduction to cross-linked polyethylene insulated power cable:

Introduction: Cross-linked polyethylene insulated power cable not only has excellent electrical properties, mechanical properties, heat aging resistance, environmental stress resistance and chemical corrosion resistance, but also has the advantages of simple structure, easy use, no laying drop limit, high long-term operating temperature (90°), and large transmission capacity.

Cross-linked polyethylene insulated power cable products include a full range of flame retardant and non-flame retardant cross-linked polyethylene insulated power cables.

This product is produced according to the company's corporate standards, which are equivalent to the national standard GB12706 and the international standards IEC60502, IEC60332, and IEC60754. Our company's corporate standards not only fully meet but also exceed some of the above national and international standards.

Flame retardant cables include A, B, C types and a full range of cables including low smoke low halogen and low smoke zero halogen.

Our company can produce high-voltage power cables according to other standards according to user needs. We can also design and manufacture cross-linked cables with special requirements such as large-section split conductors, water-blocking, termite-proof, and rodent-proof cables according to user needs.

Ⅰ. Application: Cross-linked polyethylene insulated power cable is suitable for transmission and distribution circuits with AC rated voltage of 0.6/1KV to 26/35KV, and is used for transmitting electric energy in different ways.

Ⅱ. Implementation standards:

Cross-linked polyethylene insulated power cables comply with GB/T12706-2008 standard.

Ⅲ. Usage characteristics:

1. The long-term high working temperature of the cable conductor shall not exceed 90°C.

2. When short-circuited (the longest duration does not exceed 5S), the maximum temperature of the cable conductor does not exceed 250℃.

3. The ambient temperature when laying the cable should not be lower than 0℃, and the minimum bending radius should be 20 times the cable diameter.

Ⅳ. Cable usage conditions:

1. Cross-linked polyethylene insulated vinyl chloride (polyethylene) sheathed power cables are suitable for laying indoors, in tunnels and pipelines. The cables cannot withstand external mechanical forces.

2. Cross-linked polyethylene insulated steel tape armored PVC sheathed power cable is suitable for direct burial underground and can be laid indoors, in cable trenches, tunnels and pipelines. The cable can withstand certain mechanical external forces, but cannot withstand large tensile forces.
