NXJ tie rod type insulated tension clamp
NXJ Series insulation strain clamp (wedge type)
Application:
NXJ series is suitable for strain clamp insulation string of 10KV aerial aluminum core wire JKLYJ terminal or two ends fixing and fighten aerial insulation
NXJ four-core-centralized strain clamp is suitable for the end of aerial wire terminal, it’s action is fixing or tighten the insulation conductor, the products type has NXJ-A and NXJ-B
Structure feature:
The shell made of anti-oxidate high strength aluminium alloy,Without waste power
The core of wedge made of insulating reinforce plastics,withstand voltage: ≥ 18 kV not breakdown one min.
Not need to remove the insulation layer,Al- core wire can be used directly.
Wedge structure
Performance:
The clamp has designed four core parallel groove, afteclamping the four insulation conductor (not remove the insulation layer) tighten up the bolt, have large grip strength.
