It is also wrapped on shielded layer outside edge layer, is equipped with inner support tube between the more power cable cores, on the inner support tube outer wall
Equipped with multiple arcs support element, the every power cable core is connected and fixed by curved support part with inner support tube, described interior
Support tube is internally provided with nylon rope, is additionally provided with filled layer between the more power cable cores, the filled layer, inner support tube and
The integral coating of more power cable cores composition is coated with armor, the armour in fire-retardant band outside the fire-retardant band
It is coated with enhancement layer outside dress layer, more steel wires are equipped in the enhancement layer, elastic cord breaker is coated with outside the enhancement layer,
The elastic cord breaker is internally provided with multiple cushion chambers, and multiple wear-resistant pressure-resistant items are equipped with outside the elastic cord breaker.
Further, each curved support part section is semicircle, is open towards fire-retardant band.Curved support frame has
Help improve the stability inside power cable, fixed every power cable core prevents internal loose, and promote compression strength.
Further, the multiple curved support part is uniformly distributed along inner support tube outer wall cross-sectional periphery direction.
Further, the steel wire is arranged with power cable core and is uniformly distributed along enhancement layer cross-sectional periphery direction in the same direction.
Steel wire helps to promote the tensile strength of power cable.
Further, the cushion chamber is uniformly distributed along elastic cord breaker cross-sectional periphery direction, wear-resistant pressure-resistant item edge
Elastic cord breaker outer wall cross-sectional periphery direction is uniformly distributed.Cushion chamber provides deformation space for power cable, can alleviate electricity
Stress when cable is bent or is extruded, the stress that simultaneous buffering chamber is subject to cable and inner support tube play cushioning effect, are
Inner support tube provides deformation space, increases the anti-extrusion ability and bending resistance of cable；It is resistance to when cable is when ground is drawn
Mill resistance to compression item is directly contacted with ground, and cable main body can be prevented to be worn；When cable is squeezed, wear-resistant pressure-resistant item can
Cushioning effect；In addition the setting of wear-resistant pressure-resistant item can also increase frictional force when several cables bundle, and be not easy to loosen.
Further, the cushion chamber is identical as wear-resistant pressure-resistant quantity and is oppositely arranged one by one.
The beneficial effects of the invention are as follows：The prior art is compared, a kind of anti-extrusion stretch-proof power cable of the invention passes through
Inner support tube and cushion chamber are set, promote the anti-pressure ability and bending resistance of cable, the setting of nylon rope and steel wire improves
The tensile resistance of cable.
