Abstract
The invention discloses an anti-interference multi-core shielded cable with high tensile strength. The cable includes conductors, insulating layers, a filling layer, a lapped layer, a shielding layer and an outer sheath, wherein the outer sheath wraps the shielding layer; the shielding layer wraps the lapped layer; the lapped layer wraps the filling layer; the filling layer wraps the insulating layers; the conductors are wrapped by the insulating layers respectively. According to the invention, the gap among the cable cores is filled with glass fiber threads, and then is tightened by using a glass fiber cloth wrapping belt, so that the cable is good in high temperature resistance and fire resistance, and an aluminum foil layer is good in anti-interference performance.
Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of control cables with anti-interference fire resistance.
Background technology
At present, in cable industry, fireproof control cable generally adopts the wrapped mode adding insulation of fire-resistant isinglass belt, but Mica tape class fire-resisting cable is in wrapped or bending process, mica sheet easily comes off, not by spray, vibratory test, and mica tape kind is more again now, and quality is uneven, less stable, is difficult to the fire resistant quality ensureing cable.Secondly, the insulation that common fireproof control cable uses and sheath material mostly all contain halogen or do not reach the environmental requirement of European Union ROHS instruction.Moreover the wrapped production of small bore fireproof control cable is restricted, and fire resistance quality more cannot be protected.And the poor anti jamming capability of such cable.
Summary of the invention
The object of this invention is to provide the anti-interference shielded multiconductor cable of a kind of high tensile, to overcome the technological deficiency of existing fire-resisting cable, improve the fire resistance of cable, environmental-protecting performance and interference free performance.
The anti-interference shielded multiconductor cable of high tensile of the present invention, comprise conductor, insulating barrier, packed layer, lapping layer, screen oversheath, described oversheath is wrapped in the skin of screen, described screen is wrapped in the skin of lapping layer, described lapping layer is wrapped in the skin of packed layer, described packed layer is wrapped in the skin of insulating barrier, is enclosed with conductor in described insulating barrier.
As preferably, described conductor is copper conductor.
As preferably, described insulating barrier is PVC insulating barrier.
As preferably, described packed layer is asbestos layer.
As preferably, described lapping layer is glass fiber and mica is wrapped forms.
As preferably, described screen is steel band screen.
As preferably, described oversheath scribbles wear-resisting non-metallic coating layer.
The anti-interference shielded multiconductor cable of high tensile of the present invention filled glass fiber silk in the gap of cable conductor, and tighten with glass fabric band, have well high temperature resistant and fire resistance, aluminium foil layer just has good anti-interference.
Due to refractory ceramics fire-resistant silicon rubber use working temperature higher, can reach 180 DEG C and more than, substantially increase the ampacity of cable, cable is in same ampacity situation, and cross section can reduce further.
The anti-interference shielded multiconductor cable of high tensile of the present invention has fire-resistant, environmental protection, the interference free performance of excellent electrical insulation capability, interference free performance and excellence, and processing technology is simple, and transport is laid conveniently, and cost performance is higher.
