Comparison And Selection Of Wedge-type Tension Clamps

Overview
With the rise of a new round of urban and rural power grid construction and transformation, 1~20 kV overhead insulated conductors are widely used, and various types of matching hardware have emerged one after another, with good and bad. In particular, the correct selection of dead end clamp for abc cable is crucial. As a leading company in the research and development of insulating hardware in the industry, we have focused on the energy saving, high reliability, maintenance-free and convenient installation of hardware for more than ten years. The new fungsi dead end clamp that has been continuously launched meets the requirements of non-stripping installation of insulated wires, and clamp dead end has the advantage of maintenance-free.
The composite tension insulation string consists of composite insulators, energy-saving insulation dead and clamp and connecting hardware. Its optimization scheme reduces the number of connecting parts, has the advantages of compact structure, easy installation, reliable insulation, strong pollution resistance, and significant energy saving, and is deeply loved by users.
NLL-J series bolt-type aluminum alloy dead clamp
The improved NLL-J series bolt-type aluminum alloy dead end clamp overhead line adopts high-strength aluminum alloy material and heat treatment process, and has the advantages of high strength, no hysteresis effect, and less line loss. It adopts a patented design of a self-tightening wire pressing block to avoid the slipping caused by creep of the wire insulation layer, which can meet the grip requirements of the insulated wire without stripping installation, and has the advantage of maintenance-free. An insulating cover can be added to enhance the insulation protection.
NXL-J series wedge-shaped aluminum alloy dead end clamp with eye hook
The improved NXL-J series wedge-shaped aluminum alloy dead end loop clamp, compared with the original product, has increased the radius of curvature of the wire trough and reduced damage to the wire. dead end tension clamp adopts high-strength aluminum alloy material and heat treatment process, and has the advantages of high strength, no hysteresis effect, and less line loss. It also optimizes the inner wedge design and has the characteristics of self-locking, which can meet the grip requirements of the insulated wire without stripping installation, and has the advantage of maintenance-free. An insulating cover can be added to enhance the insulation protection.
The products are divided into single-ear type (default) and double-ear type (indicated by adding the letter S after the model) according to the different connection rings to meet the matching installation with different hardware and insulators.
NEJ series wedge-type insulation fiber optic dead end clamp
The improved NEJ series wedge-type insulation fixed dead end clamp has a more suitable inner wedge angle, which produces greater grip on the wire and transmits it to the wire core. It has a more refined and compact appearance, higher strength, and lower line loss; and a more optimized specification classification has been made to improve the adaptability to the outer diameter differences of the same specification wires from different manufacturers. Due to the use of a double inner wedge structure, the grip on the wire is proportional to the tension, the self-tightening effect is more reliable, and the operation is maintenance-free. The inner wedge is made of weather-resistant reinforced engineering plastics, with an AC withstand voltage of 45kV, and the pressure is maintained for 1 minute without breakdown and flashover.
