Abstract
The utility model discloses a three-core-group flexible cable with a composite shielding layer. The three-core-group flexible cable comprises a middle flexible body, wherein the flexible body is cross-shaped and composed of thermoplastic elastomers with a plurality of uniformly-arranged through holes; the periphery of the flexible body is divided into four parts by the elastomers, and a thick conductor and two thin conductors are arranged in each part; a lapping layer is wound outside the three conductors; the peripheries of the lapping layer and the elastomers are sleeved with a composite shielding layer; the composite shielding layer is composed of an inner nylon belting layer and an outer aluminium-plastic composite belt layer; and a sheath layer is arranged outside the composite shielding layer. The three-core-group flexible cable disclosed by the utility model is stable in design structure, and provided with an elastic function to a certain extent in case of bearing an external force; moreover, the outside composite shielding layer is provided with a good shielding function, thus effectively protecting the overall structure of the cable against breakage and interference and ensuring electricity safety.
Description
Technical field
The utility model relates to electric wire field, and concrete is a kind of three core group flexible cables with composite shielding layer.
Background technology
That a variety of power cables are laid on is indoor, in tunnel, cable trough and pipeline, cable can not bear excessive mechanical external force effect, so this class cable just need to allow cable have certain external force ability to bear in the process manufacturing and designing, or the elasticity with self, to guarantee the safety of cable.
Utility model content
The utility model provides a kind of structural design cleverly with three core group flexible cables of composite shielding layer, has certain elasticity, guarantees the work of the safety of cable.
The technical solution of the utility model:
The three core group flexible cables with composite shielding layer, the flexible body that comprises middle part, it is characterized in that: described flexible body is to be " ten " word shape, by thermoplasticity, form with some elastomers of evenly arranging through hole, elastomer is divided into four parts around by it, in each part, be equipped with thick two thin three conductors, three conductors are around with lapping layer, lapping layer and elastomeric outer race have composite shielding layer, composite shielding layer is comprised of nylon bag belt and the outer field plastic-aluminum combined belt of internal layer, and composite shielding layer is provided with restrictive coating outward.
The described three core group flexible cables with composite shielding layer, is characterized in that: in described lapping layer and the space between elastomer, be provided with filler.
Advantage of the present utility model:
The utility model project organization is stable, and when cable bears external force, it has certain elastic reaction, and outside composite shielding layer has good shielding action, has effectively protected the overall structure of cable be not damaged and disturb, and has guaranteed Electrical Safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
