A kind of Intelligent insulation cable penetrating cable clamp
Technical field
The invention belongs to technical field of electric equipment, are related to a kind of insulated cable penetrating cable clamp.
Background technique
Insulation puncture line clamping is mainly by two split glands, piercing blade, the bolt across two glands, torque nut
Deng composition.When cable need to do branch or connect, after determining main line branch location, the torque spiral shell on wire clamp is twisted with box spanner
Mother contacts blade meeting penetrating insulating layer of cable in the process, contacts with conductor, and gasket ring voltage cable is punctured around position,
When torque reaches setting value, nut moment explosive separation, main line and branch line are switched on.With simple installation, low cost, safety
Reliable non-maintaining feature.Insulating layer it is not necessary that leader cable is truncated, without peelling off cable can do cable branch, and connector is completely exhausted
Edge, can livewire work, live branch can be made in cable any position.Without the use of termination rack, coupling box.But it is existing exhausted
Edge penetrating cable clamp is during installation, laborious by bolt tightening gland, especially when carrying out remote-controlled operation using insulating bar;Separately
