Outside stranded conductor, be provided be beneficial to identical with conductor material forms shiny surface, strengthens conductance between the lead conductor shield.
Be disposed with crosslinked polyetylene insulated layer, shield semiconductors layer, inner sheath, main shield ground plane, protective layer, steel armour layer, insulating sleeve outside described conductor shield, described steel armour layer is for supporting the armour body, with the carrying cable transverse pressure.
Described support armour body is spiral steel armour or metal bellows.
Transition joint that is applied to above-mentioned flexible hollow cable and terminal fitting among the present invention, its design feature is: described transition joint and terminal fitting by can directly overlap be pressed in the outer sleeve pipe of the hollow arrangement lead of cable and in chock two parts that are lining in the cable voided layer of emptying the lightweight elastic form, described chock and sleeve pipe are conductor; Sleeve pipe one end of described terminal fitting has the coupling part of the connecting hole of adorning screw.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the lead of cable of the present invention adopts hollow arrangement mode, to utilize the kelvin effect of alternating current, effectively utilizes the cross section of conductor, and AC resistance is little, and power loss is little.
2, the hollow arrangement of lead of the present invention makes cable outer contacting face big, and radiating condition is good, and the cable temperature rise is low, is beneficial to the conductor material heat radiation, thereby guarantees the normal useful life of cable.
3, the present invention adopts the lightweight elastic material to fill the lead voided layer with load intensity auxiliary and the reinforcement cable; Satisfy the suppleness of cable, the lateral stress of carrying cable at the outer winding screw shape steel armour (or ripple struction) of lightweight elastic material; Adopt helical spring to support voided layer and can strengthen the cable flexibility, flexible, easily produce.
4, the present invention also is provided with crosslinked polyetylene insulated layer, shield semiconductors layer, inner sheath, main shield ground plane, protective layer safeguard measure outside hollow conductor; make cable go for multiple occasion, outside protective layer, install the armour body additional with further protection cable and carrying cable lateral stress.
5, the present invention is provided with a kind of hollow core cable joint simultaneously, and it is convenient on the one hand the hollow core cable two ends to be connected, and the resistance value of tie point is reduced, and improves the circuit running quality.
6, flexible hollow cable quality of the present invention is light, and it is longer that the cable of the packing of product, transportation and easy for installation, particularly equal quality can be done, and reduces the transition joint number.
