The NEJ, JNE (NXJ, JNX) wedge type insulated tension clamp is suitable for fixing and tightening the overhead insulated wire on the tension insulator at the terminal or both ends of the tension section of the rated voltage 10kV and below.
structural characteristics
The wedge-shaped structure has a gripping force proportional to the pulling force on the wire, with self tightening characteristics and maintenance free operation.
The C-shaped shell of the wire clamp is made of high-strength, anti alumina alloy die-casting, without hysteresis or eddy current, making it an energy-saving metal fitting.
The C-shaped opening design of the shell makes it easy to insert the inner wedge and wires, and the installation is convenient and fast.
The inner wedge is made of weather resistant insulation reinforced engineering plastic, applied with AC withstand voltage of 45kV, and maintained for 1 minute without breakdown or flashover.
Special Notice
When selecting, the actual outer diameter of the applicable wire should be determined first, as insulated wires are classified into 10kV and 1kV voltage levels, as well as thin insulation, thick insulation, and whether they have a steel core.
