NXL series wedge-type tension clamp is used for 20kV and below distribution lines to fix the overhead insulated aluminum conductor or bare aluminum conductor onto the corner or insulater on the terminal resistance rod; so that the overhead conductor is fixed or tightened. The clamp works with insulation cover to offer inuslation protection.
