35KV-220KV rubber material high voltage red overhead line cover

35KV-220KV rubber material high voltage red overhead line cover

 

 

Description

 

RUBNS-OLC  design, ease of installation. Use silicon rubber material, anti-aging, corrosion resistance, with good resistance to corona resistance, high temperature performance, especially suitable for the protection of the bare wire. High voltage red overhead line cover is widely used in substation protection works and railway catenary system, a significant effect in the cross-lines.

Installation Instructions

 

Clean the inside of the RUBNS-OLC with cleaning cloth and alcohol fluids until the inside is

clean without dust;

Connect the pointed plastic mouth to the body of RTV Silicone Rubber adhesive bottle. Seeillustration 1 above.

 

Smear RTV silicone rubber adhesive all over the concave channel of the RUBNS-OLC

 

uniformly as showed in illustration 2 above

 

Uniformly smear the two flat fringes of the concave channel with RTV silicone

 

rubber adhesive as the illustration 3 shows

 

Connect the bulging part of the RUBNS-OLC on one side into the concave channel of the

 

other side and squeeze the connecting part from one end to the other as illustration 4 indicates
