product mix

The components from inside to outside are conductor, insulation layer, filling layer, (steel layer) and sheath layer. The most commonly used conductor on the market today is, of course, copper conductor; the insulating layer and the outer sheath material are PVC plastics; the filling layer is generally some softer nylon materials, in order to prevent direct contact between the conductors of the cable extrusion; steel armored VV cable for VV22 cable, steel strip The role of armour is compressive and can be used for burying.

GB/T12706.1-2008;

Rated voltage

Generally 0.6/1KV or below 35KV;

working temperature

The permissible maximum temperature of cable conductor in short circuit (the longest duration is not more than 5s) is 160 C.

Allowable bending radius

It is not less than 10 times the diameter of the cable.

purpose

Usually used as a power transmission hub, often buried in soil or laid indoors, ditches, tunnels, insulation distance between lines is small, do not use towers, occupy less land, basically does not occupy the ground space.
