High Voltage cable
HV XLPE cables for power frequency AC voltage 500KV and below transmission and distribution lines. Currently the vast majority have adopted the high-voltage cables XLPE insulation.
XLPE cable usually refers to cable insulation using crosslinked material. The most commonly used material for the cross-linked polyethylene (XLPE). Cross-linking process is linear molecular structure of polyethylene (PE) through a specific way of processing the material, to form a cross-linked polyethylene mesh size sub-line structure. So that long-term allowable working temperature increased from 70 ℃ to 90 ℃ (or higher), short-circuit allows the temperature increased from 140 ℃ to 250 ℃ (or higher), while maintaining excellent electrical properties of its original premise, greatly improve the actual performance.
This product is suitable for 66KV-220KV high voltage,extra-high-voltage transmission and distribution line.
Mechanical properties and electrical performance accord with IEC60840 and IEC62067 standard,

3. 66kv-220kv XLPE insulated electric cable description of the process
Conductor is copper or aluminum.
Conductor cross section 800mm² and below layers of pressed manner using good conductor roundness, pressed factor.
1000 mm² conductor cross-section and is divided over the use of the conductor, effectively reducing the skin effect of the conductor set,
increase the carrying capacity of the cable. For my company's largest division conductor cross section 3000mm² .
Conductor material can be twisted into the swelling to achieve watertight along the conductor.
