LH type cable sheath protectorDetailed product description：

LH type cable sheath protector (LH)

Medium and high voltage cables are often forced to reduce their transmission capacity due to the breakdown and damage of the outer protective layer caused by the induced voltage of the metal sheath.
In order to reduce the overvoltage of the sheath to ground and avoid the breakdown of the outer protective layer, a protective layer protector is commonly used to limit the voltage and ensure the reliable operation of the cable.

The LH cable sheath protector is applied in single core power cable lines to limit the induced overvoltage on the metal sheath of the cable, ensuring that the insulation of the protective layer is not broken down by overvoltage. This product can be used in grounded cable lines and cross connected cable lines.
