Abstract
The utility model provides an insulating steel wire armouring power cable of polyvinyl chloride belongs to cable technical field. Still there is the defect in the structure that it had solved most cable, for example the structural hierarchy design is unreasonable, and the structure is compact inadequately between each layer, the more single scheduling problem of conductor aspect ratio. This insulating steel wire armouring power cable of polyvinyl chloride, including a plurality of heart yearns, the outside package of a plurality of heart yearns is equipped with steel wire armoring layer, and it has the filler to fill between steel wire armoring layer and a plurality of heart yearn, steel wire armoring layer's the outside be equipped with shielding layer and restrictive coating in proper order, the outside that is located the restrictive coating is equipped with fireproof coating layer, the restrictive coating be polyvinyl chloride insulating sheath layer, the utility model has the advantages of overall structure is compact, coordinates closely between layer and the layer, and structural strength is high, and is not fragile, is provided with fireproof coating layer and is used for the fire prevention, is provided with the shielding layer and can shields electromagnetic field and ground protection function, uses safe and reliable, long service life.
Description
Technical field
This utility model belongs to field of cable technology, refers in particular to a kind of polyvinyl chloride insulation steel wire armored power cable.
Background technology
The at will fast development of national economy, as the electric wire of national economy aorta, its consumption and range are increasing.At present, cable type on market is various, they apply in all trades and professions, different occasion, but the structure of major part cable still suffers from defective, such as layer of structure design is unreasonable, and between each layer, structure is the compactest, conductor shape is more single, the Rotating fields easily causing cable is the most impaired, and using effect is undesirable, causes service life the shortest.
Summary of the invention
The purpose of this utility model is to provide a kind of polyvinyl chloride insulation steel wire armored power cable, its compact conformation, and intensity is high, is hardly damaged, and service life is long.
The purpose of this utility model is achieved in that
