Description
Technical field
The utility model relates to field of cable technology more particularly to a kind of 26/35kV and following Cable for frequency changer.
Background technique
As society constantly advances, user is also higher and higher to cable performance requirement, uses especially for frequency converter
Field of cables, it appears more outstanding.But currently, existing cable, in cable master core arrangement be not in dot symmetrical structure,
Shield effectiveness is bad, and cable is disturbed seriously, and ac magnetic field is unstable, and Wave crest and wave trough cannot be offset；Inside existing cable
Structure is not sufficiently stable, and is easily deformed in use process.
Utility model content
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of 26/35kV and with low-converter
Use cable.
The utility model is achieved through the following technical solutions:
A kind of 26/35kV and following Cable for frequency changer, include core, and the core includes conductor and successively
Conductor shield, insulating layer, insulation screen, copper strips lapped shielding layer and the round rubber frame being coated on the outside of conductor, institute
The wrapped Duplication for the copper strips lapped shielding layer stated is greater than 25%, is equipped on the outer wall of the round rubber frame multiple convex
It rises, will successively be coated with Halogen glass fibre belting layer, separation layer, galvanized steel strip or aluminium alloy on the outside after three core bundle strands
Band armor and restrictive coating.
The conductor shield is the plastic shielded layer of semiconductive.
The insulating layer is crosslinked polyetylene insulated layer or ethylene-propylene rubber insulated layer.
The insulation screen is the plastic shielded layer of semiconductive.
The separation layer is polyvinyl chloride separation layer or polyethylene isolation layer or crosslinked polyethylene separation layer.
The restrictive coating is polyvinyl chloride oversheath or polyethylene outer sheath or crosslinked polyethylene oversheath.
The utility model has the advantages that: the utility model squeezes out conductor shielding half by three-layer co-extruded successively extrude by conductor
Conductive layer, profiled insulation, insulation semi-conductive screen constitute insulated wire cores, and insulation shielding effect is good, and the connection of core internal structure is tight
It is close, it is unlikely to deform, multiple protrusions is equipped on the outer wall of the round rubber frame, are not easy the position between each core
It changes, structure is more stable, is squeezed out after separation layer adds armouring after insulated wire cores stranding band and squeezes out sheath composition cable, signal passes
Defeated stabilization, use are safe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of 26/35kV and following Cable for frequency changer, include core, the core includes to lead
Body 1 and conductor shield 2, the insulating layer 3, insulation screen 4,5 and of copper strips lapped shielding layer for being successively coated on 1 outside of conductor
The wrapped Duplication of round rubber frame 6, the copper strips lapped shielding layer 5 is greater than 25%, in the round rubber frame 6
Outer wall be equipped with multiple raised 7, will be successively coated on the outside after three core bundle strands Halogen glass fibre belting layer 8, every
Absciss layer 9, galvanized steel strip or aluminum alloy strip armor 10 and restrictive coating 11.
The conductor shield 2 is the plastic shielded layer of semiconductive.
The insulating layer 3 is crosslinked polyetylene insulated layer or ethylene-propylene rubber insulated layer.
The insulation screen 4 is the plastic shielded layer of semiconductive.
The separation layer 9 is polyvinyl chloride separation layer or polyethylene isolation layer or crosslinked polyethylene separation layer.
The restrictive coating 11 is polyvinyl chloride oversheath or polyethylene outer sheath or crosslinked polyethylene oversheath.
