Description:
NXJ (JNE) series wedge-type insulated tensile clamps are suitable for fixing and tightening overhead insulated conductors on the ends of the end of the overhead insulated conductors with rated voltages of 10kV and below or the ends of the tensile sections or the ends of the tensile sections.
Structure:
1.The wedge-shaped structure is proportional to the pulling force of the wire and has the characteristics of self-tightening, and the operation is maintenance-free.
2.The C-shaped shell of the clamp is made of high-strength, anti-oxidation aluminum alloy die-casting, without hysteresis and eddy current, and is an energy-saving fitting.
3.The shell C-shaped opening design makes the inner wedge and the wire easy to install, and the installation is convenient and quick.
4.The inner wedge is made of weather-resistant insulation-reinforced engineering plastics, with an AC withstand voltage of 45kV and a pressure of 1 minute without breakdown and flashover.
Notes:
When selecting the type, the actual outer diameter of the applicable wire should be determined first. Because the insulated wire is divided into 10kV and 1kV voltage levels, there are thin insulation, thick insulation and steel core.
Features:
1. C-shaped opening design, easy to install, no closed magnetic ring, lower energy consumption
2. Insulated inner wedge with anti-slip groove for greater grip and no damage to the wire
3. Elliptical cone structure, uniform stress, higher strength, more material saving and less energy consumption than square
4. Smaller inner wedge angle, greater grip, allowing more grip to be transmitted to the core
5. The internal wedges that are engaged with each other are more convenient to install and prevent one-side sliding
6. Horizontal screw, stronger tensile strength
7. Pull plate 360° rotation design for easy installation and transportation
8. Top wire loop ring, which can be connected with the tensioner for easy construction
9. More compact connection, reduced coupling fittings

Special attention: When the overhead insulated steel-cored aluminum stranded wire is installed in a short span (within 50 meters), the product model specification can be selected according to the outer diameter of the wire and the required grip strength, but the grip force is not more than the wire pull-out force. 65% of requirements
The NXJ2 screw wedge tension clamp is an economical version of the NXJ series. It replaces the original JNE2 series and has the advantage of lower cost. However, the installation is slightly inconvenient and suitable for rural power grids
