Import 500 Kv Xlpe Insulated Power Cable — Buy in wholesale FOB from Supplier in China

Cangzhou Huiyou Cable Stock Co., Ltd manufactures 500 kV XLPE insulated power cable to Chinese national standard GB/T 22078.2-2008. The rated voltage structure is U0=290 kV, U=500 kV, Um=550 kV, designed for single-core installation under normal operating conditions. The maximum continuous conductor temperature is 90 degrees Celsius, with short-circuit withstand of 250 degrees Celsius for up to 5 seconds. This cable is explicitly not intended for submarine or other special-use applications. The supplier operates from the New Huiyou Industry Zone in Hejian City, Hebei Province.

XLPE (cross-linked polyethylene) insulation provides excellent dielectric strength and thermal stability for extra-high-voltage transmission. The cross-linking process creates a thermoset material that retains mechanical properties at elevated temperatures where thermoplastic insulation would deform. Typical conductor materials for this voltage class include stranded copper or aluminium, with corrugated aluminium or lead sheath and polyethylene outer jacket. The 500 kV class demands precision in insulation thickness, semiconducting layer interfaces, and void control during extrusion. Standard factory tests include partial discharge measurement, AC voltage withstand, and impulse tests per applicable standards.

Utility companies, grid operators, and large industrial power projects are the primary buyers for this cable category. Installation requires skilled jointing teams and careful handling to preserve insulation integrity. The listing does not specify conductor cross-sectional area, armour type, or exact cable construction. Buyers should request detailed technical datasheets and factory inspection reports. Payment terms and specific delivery schedules are not stated in the source and must be confirmed directly with the supplier.

Cangzhou Huiyou Cable Stock Co., Ltd is located in the New Huiyou Industry Zone, Hejian City, Hebei Province, China, with postal code 062450. The company's trust tier is harbour, with a response rate of 0.00% and zero average response hours recorded. These metrics indicate limited reliability for rapid communication, so buyers should plan for direct follow-up and possibly engage through trade representatives or agents familiar with Hebei cable manufacturers.

The supplier produces power cable to Chinese national standards, specifically GB/T 22078.2-2008 for the 500 kV XLPE line. No information is provided about year of establishment, factory floor area, annual production capacity in kilometres, number of employees, revenue, export destinations, or major reference projects. The listing does not mention ISO 9001, ISO 14001, or other management system certifications. Buyers should request a company profile, factory audit reports, and reference installations before committing to large procurement.
