50/66KV Copper Conductor, XLPE insulation Corrugated Aluminum Metalic Sheath and PVC Sheath EHV Cable
 

Application:

This product is suitable for 66KV-220KV high voltage,extra-high-voltage transmission and distribution line.

Operating character:

1). conductor

conductor is copper or aluminum. Conductor cross section 800mm² and below layers of pressed manner using good conductorroundness, 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 section3000mm² .Conductor material can be twisted into the swelling to achieve watertight along the conductor.

2). insulation

Conductor shield, insulation, insulation shield while using VCV three towers stand out. Company Vertical high crosslinking shop 129m,shop built with three vertical cross-linked production lines, three production lines were imported from Finland and Germany TROESTERMaillefer company. Three production lines are equipped with front and rear pre-heating system, which can effectively remove moistureinside the conductor, insulation and more uniform heating. Production lines are equipped with German Skikora online corneringinstrument to control the insulation eccentric to a minimum. Online stress relief system can effectively reduce the insulation core internalresidual stress, and further improve the electrical and mechanical properties of the cable. Three production lines are all-dry crosslinkingand cooling.

3). insulation to gas

Due to the high pressure, high pressure cross-linked polyethylene insulated power cable insulation thicker, will produce crosslinkedbyproducts under high temperature and pressure conditions crosslinking,
