Specification

nductor

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.

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 TROESTER Maillefer company. Three production lines are equipped with front and rear pre-heating system, which can effectively remove moisture inside the conductor, insulation and more uniform heating. Production lines are equipped with German Skikora online cornering instrument to control the insulation eccentric to a minimum. Online stress relief system can effectively reduce the insulation core internal residual stress, and further improve the electrical and mechanical properties of the cable. Three production lines are all-dry crosslinking and cooling.

3.insulation to gas

Due to the high pressure, high pressure cross-linked polyethylene insulated power cable insulation thicker, will produce crosslinked byproducts under high temperature and pressure conditions crosslinking, in order to accelerate the release of crosslinked byproducts crosslinking core money into the next production process To enter the insulated core heated drying room for de-gas treatment. Accelerate the gas discharge, effectively reduces the possibility of the cable laying operation occurring during accidents.

4. Watertight layer and the buffer layer

To cushion the cable insulation during operation of the thermal expansion and achieve waterproof cable between the insulation shield and the metal sleeve has a buffer water blocking layer, the adoption of good cushioning properties of semiconducting expansion buffer water blocking tape wrapped in insulation, semiconductive water resistance with uniform conductivity, and leave the cable core can absorb in a short circuit load cycle core temperature and margin expansion between the metal sheath and the buffer layer.

5. Corrugated aluminum sheath

The company's production process is a metal sleeve jacket clad aluminum extrusion and aluminum welding sets in two forms. Can be produced according to the user's needs. Aluminum sheathed cable short circuit capacity to meet the requirements, but also has a light weight, high strength, easy to bend characteristics, but also has excellent waterproof performance. Aluminum sheathed cables outside as corrosion layer of asphalt or hot melt adhesive.

6.outer sheath

Outer sheath of PE or PVC, are also available upon request retardant, anti-termite, low smoke and low halogen flame retardant, low smoke zero halogen flame-retardant material, while the outer jacket extruded semi-conductive layer, as the outer sheath electrode voltage test sets.
