Preferably, the steel core and bracket, which are integrally formed, is arranged.

Preferably, the conductor is twisted by several copper wire.

Preferably, flexible rubber item is equipped between the core and bracket.

Preferably, the filled layer is glass layer.

Preferably, the inner sheath and oversheath are low-smoke halogen-free polyolefin restrictive coating, and the reinforcing rib is in the shape of a spiral Setting.

Compared with prior art, the utility model has the beneficial effects that the utility model passes through the setting of steel core and bracket, Play the role of carrying to core, the construction of cable can be made firmer, prevent cable from causing core to damage by extruding；

It is the setting of glass layer by filled layer, improves high temperature resistant, fire protection flame retarding and the corrosion resistance of cable；

By the setting of the first crosslinked polyetylene insulated layer and the second crosslinked polyetylene insulated layer, so that the insulating properties of cable Higher, use is safer；

It include the setting of inner sheath, reinforcing rib and oversheath by restrictive coating, wearability and the tension for improving cable are strong Degree.
