RUBNS-OLC
Silicon Rubber Overhead Line Cover
For Input line and Output line of power transmission and transformation stations, when there is high wind
which swing the bare cables too close, short-circuit trouble will happen. With Silicone Rubber Cover, it can
avoid the short-circuit.
Silicone Rubber Cover can insulate and protect the bare cable from the corrosion of bird guano, salt mist and
other acid and basic rain.
For complex living area, the overhead line are crossed very complex, once there is conductor like steel get
touch with the line, troubles will happen.
Effectively prevent short circuit caused by something electric overlap.
PLN Indonesia used our silicone rubber hose to prevent the Kite of children.
Much lighter in weight than other flexible dielectric coverup, helps protect workers from accidental contact
with conductors.
With Red, Green, Yellow colors, cables can be easily identified. Saving the cost of maintain and repairmen.
Silicone Rubber Overhead Line Cover is your best choice for Bare Cable insulation and protection, easy handle,
install fast. Short the maintain time when you have to cut all power, saving cost.
Compate to PVC Insulation Sleeve, silicone rubber is much environment friendly. PVC can only work under
105 degree, silicone rubber can continuous work under 150 degree. Also silicone rubber is anti-aging and
Description
RUBNS-OLC The innovative product 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. Widely used in substation
protection works and railway catenary system, a
significant effect in the cross-lines.
Features

corrosion resistant.
Compare to PE Insulation Sleeve, the Silicone Rubber hose is much longer at the shelf life. Because silicone
rubber is acid and basic retardant, anti-aging, corrosion resistance and also high temperature retardant. PE
can not meet these requirements very well.
Compare to tape, the silicone rubber cover is more easy to install, more sealing when there is water.
