35kV Cold Shrinkable Cable Accessories
Description
Performance Characteristics
Cold Contracted Technology:
Advantage of using rubber "elastic memory", with advanced technology of expansion, will produce the good cable terminal rubber pieces open in advance within the elastic range, set into the plastic support. When installation, only need to remove plastic support bar, cable terminal rubber parts will rapidly shrink hold on the cable.
Reliable Insulation:
Raw material is imported from international famous companies of high quality liquid silicon rubber, reliable insulation performance, reliable and excellent electric properties. Silicone rubber materials, antistatic mark and strong corrosion resistance, long service life. Stress cone strengthened the margin design,insulation performance is more reliable.
Easy Installation:
All cable terminal rubber parts have been preformed in our factory, as long as according to the operating instructions for installation; Without professional installation tools, convenient; No flame operation, safe and reliable.
Advanced Equipment:
In purifying air conditioning workshop, cable accessories are produced by computerized automation production equipment imported from Switzerland. Based on 200 kV full screen no discharge laboratory to test the performance of cable accessories, ensure the quality of the product.
Widely use:
Because of the characteristics of the silicone rubber, flth resistance, aging resistance, good Hydrophobic performance, cold resistant performance, cable accessories are suitable for high altitude area, wet and cold areas, smog and heavy pollution areas, etc., especially suitable for petroleum, chemical industry, mining and other inflammable and explosive industries.
