Abstract
An environment-friendly composite screened control cable is characterized in that a conductor is formed by twisting one or a plurality of tin plated coppers; a silane crosslinked polyethylene insulating layer is extruded on the conductor so as to form insulated conductor cores; a plurality of insulated conductor cores are twisted to form a cable and an antiflaming glass fiber filling layer is arranged so as to form a cable conductor; and the cable conductor is externally provided with a lapping band layer, a composite shielding layer, a lining layer, a double-layer steel tape armour layer andan outer sheath layer in sequence, wherein the inner layer of the composite shielding layer is a tin plated copper weaving layer, and the outer layer thereof is a longitudinal lapping or lapping aluminum or copper-plastic cladding strip layer. The environment-friendly composite screened control cable has excellent electrical property and mechanical property, and antiflaming property, is heat resisting, environment-friendly, soft and anti-interference.
Description
Technical field
The utility model relates to a kind of electrical equipment control cable, relates in particular to a kind of environment-friendly type composite shielding control cable, belongs to technical field of electric wires and cables.
Background technology
Control cable is mainly used in the control loop between the electrical equipment, as the connecting line between all kinds of electrical instrumentations and the automation equipment, plays a part various electric energy of transmission or control signal, makes whole electrical system obtain safe and reliable operation.More and more higher and along with the automaticity of electrical equipment to the attention of environmental protection, require the control cable of the connecting line between electrical instrumentation, the automation equipment etc. to have fire-retardant, high temperature resistant, environmental protection, softness, performance such as anti-interference, guarantee that electric property and machinery are good simultaneously again to wait requirement.
At present, the structure that adopts of the screen of the anti-electromagnetic interference that adopts of control cable has forms such as aluminium/plastics composite belt longitudinal bag overlap joint, copper wire or tinned copper wire mesh grid and copper strips be wrapped.
Aluminium/plastics composite belt longitudinal bag bridging arrangement has shielding action preferably, and low cost of manufacture, but because aluminum layer thickness is thin, not tight behind two edge laps of vertical bag back, electromagnetic wave can pass and leak from the slit, and the shielding rejection coefficient is not high, and application is restricted; Copper wire or tinned copper wire mesh grid make simultaneously that efficient is low, cost is high because sealing is poor, and shield effectiveness is undesirable; Copper strips shielding flexibility is poor.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of have good electric property and mechanical performance are provided, fire-retardant, high temperature resistant, environmental protection, softness, jamproof environment-friendly type composite shielding control cable.
The utility model adopts following technical scheme:
The design feature of the utility model environment-friendly type composite shielding control cable is that conductor is single or adopts the many stranded formations of tinned copper wire, extrudes the poly-second insulating barrier of crosslinked with silicane and constitute insulated wire cores on conductor; By the stranded stranding of many eradications edge core and flame-proof glass fibre silk packed layer is set constitutes cable conductor; Outside cable conductor, set gradually wrapped belting layer, composite shielding layer, inner covering, double-deck steel band armour and external sheath layer; The internal layer of composite shielding layer is a tincopper fuse wire braided armor, and is outer for indulging bag or wrapped aluminium or compound copper-plastics band layer.
Design feature of the present utility model also is: described belting layer adopts the belt polyester material; Described inner covering and external sheath layer be with the TPU elastomer for extruding material, or with low smoke halogen-free flame-retardant polyolefin for extruding material.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model insulating barrier adopts the poly-second insulating material of crosslinked with silicane, the insulation resistance height, and dielectric loss is less, and the highest long-term permission serviceability temperature of conductor can reach 90 ℃, and material is easy to get, and is easy to process, and cost performance is the highest;
2, screen adopts tinned copper wire braid shielded and aluminium (copper) to mould vertical bag or wrapped formation composite shielding layer in the utility model, and shield effectiveness is good, and cable is soft more; Tinned copper wire is better than the anticorrosive property of bare copper wire simultaneously, has guaranteed the electric stability of electrical equipment and cable contact position;
3, belting layer adopts the polyester strip material in the utility model, and it has high-intensity performance on the one hand, plays the wrapping insulated wire cores, and the polyester belt electrical property is good on the other hand, has improved the electric property between insulating barrier and the screen;
4, the double-tape armor layer has played mechanical protection effect and antimagnetic interference effect in the utility model;
5, inner covering and external sheath layer adopt low-smoke and halogen-free flame retardant polyolefin jacket material or TPU elastomeric material, environmental protection, safety, recyclable repeated use in the utility model.
