    Features
    • This link box is used for the cross bonding of the metal sheath of the single-core cable by limiting the surge overvoltage on both sides of the insulation segment of the metal sheath and the insulation joint, controlling the induced voltage of the metal sheath, and lowering (or eliminating) the eddy current on the sheath layer. This can prevent the breakdown of the cable outer sheath and make sure the safe operation of the cable;
    • The sheath is made of 304 stainless steel, the interior of which can be filled with resin;
    • Small volume, light, easy to install and the sheath protector can be replaced.
