Features
This product is suitable for cross-bonding of metal sheaths of high-voltage single-core power cables, limiting the rise of switching overvoltages across the insulating sections of the sheath and insulating joints, controlling the induced voltage of the metal sheath, reducing or eliminating circulating currents in the sheath, increasing the cable's transmission capacity, preventing breakdown of the cable's outer sheath, and ensuring safe operation of the cable. The product features a protective enclosure made of stainless steel, with resin that can be poured inside; it is small in size, light in weight, easy to install, and the sheath protection device is replaceable.
