Abstract

The utility model relates to an anti-interference environment-friendly computer cable. A layer of 125 DEG low-smoke halogen-free flame-retardant cross-linked insulation sheath is extruded outside an inner conductor made of multiple strands of silver plated copper wire or multiple strands of tinned copper wire to form an insulated sheath wire; two insulated sheath wires are twisted in pairs and are wrapped sequentially with a layer of aluminum foil shielding tape sub shielding layer and a flame-retardant mica tape to form a complete twisted pair; at least one twisted pair is braided with a layer of silver plated copper wire or tinned copper wire overall shielding layer; and a layer of 125 DEG irradiation cross-linked low-smoke halogen-free flame-retardant outer sheath is extruded outside the overall shielding layer. The anti-interference environment-friendly computer cable has the advantages of small interference, light weight, small pollution, good performances, good fire resistance, and stable signal transmission.

Description

A kind of jamproof environment-friendly type computer cable
Technical field
The utility model relates to a kind of cable, is particularly applied to the signal transmission of industrial and mining enterprises' distributing systems such as generating, metallurgy, petrochemical industry, electronic computer system, automated system and a kind of jamproof environment-friendly type computer cable of detecting instrument instrument.
Background technology
Extensive use along with computer electronic technology, the particularly application of the transmission of the signal of industrial and mining enterprises' aspect distributing system such as generating, metallurgy, petrochemical industry, electronic computer system, automated system and detecting instrument instrument, proposes higher requirement to the stability of signal transmission and the fail safe in use procedure.And these enterprises are all located in remote mostly, and infrastructure is imperfection comparatively speaking, cause relevant device and system-operating environment complicated.The aspect performances such as the at present anti-jamming effectiveness of general structural material that computer cable adopts, fire-resistant and environmental protection are all very limited, cannot meet the nowadays extensive use of computer electronic technology.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of anti-jamming effectiveness good, high safety, and environmental and durable a kind of jamproof environment-friendly type computer cable.
The utility model for achieving the above object, the technical scheme adopting is: a kind of jamproof environment-friendly type computer cable, it is characterized in that: the conductor that included is extruded the insulating sleeve line that one deck 125 degree low-smoke non-halogen flame-retardant cross linked insulation sheaths form outward, it is right that two eradication edge RVV are twisted into, outside it, wrapped one deck aluminum foil shielded band divides screen successively, fire-resistant isinglass belt is combined into complete twisted wire pair, also comprise total screen, oversheath, described at least one pair of, twisted wire externally weaves the total screen of one deck, at total screen, extrude one deck 125 degree irradiated crosslinking low-smoke and halogen-free flame retardant oversheaths outward.
The beneficial effects of the utility model are:
1, disturb little: the utility model adopts minute to shielding and total shielding double-decker, has reduced the interference to signal transmission of external magnetic field and internal magnetic field, shield effectiveness large increase.
2, lightweight: 125 degree low-smoke non-halogen flame-retardant cross linked insulation materials are as insulating sleeve, and 125 degree irradiated crosslinking low-smoke and halogen-free flame retardant materials, as crust restrictive coating, have reduced the weight of product greatly, facilitate cable laying.
3, pollute little: 125 degree low-smoke non-halogen flame-retardant cross linked insulation materials are as insulating sleeve, and 125 degree irradiated crosslinking low-smoke and halogen-free flame retardant materials, as crust restrictive coating, only produce the gas of a small amount of LSZH when burning, belong to environmentally friendly machine.
4, performance is good: 125 degree irradiated crosslinking low-smoke and halogen-free flame retardant materials, as oversheath, have improved current-carrying capacity of cable, working temperature grade and physical and mechanical properties, and cable operate power also obviously improves.
5, fire resistance is good: divide shielding outer wrapped one deck fire-resistant isinglass belt, effectively ensure when crust catches fire inner wire is not caused to damage, reduce because of the cable impact on equipment on fire.
6, stable signal transmission: inner wire adopts multiply silver-plated copper monofilament or multiply tin-coated copper monofilament, not only improves the electric conductivity of conductor, has also improved corrosion resistance and the non-oxidizability of copper conductor simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right structural representation of the utility model twisted wire.
Embodiment
As Fig. 1, shown in 2, jamproof environment-friendly type computer cable, can obtain by following technical process manufacture: use bunching machine stranded multiply silver-plated copper monofilament or multiply tin-coated copper monofilament as inner wire 1-1, outside inner wire 1-1, adopt 125 degree low-smoke non-halogen flame-retardant cross-linked materials to extrude one deck insulating sleeve 1-2 and form insulating sleeve line, it is right that two eradication edge RVV are twisted into, outside it, wrapped one deck aluminum foil shielded band divides screen 1-3 successively, fire-resistant isinglass belt 1-4 is combined into complete twisted wire to 1, at a pair of or multipair twisted wire to the 1 total screen 2 of outer braiding one deck silver-gilt copper wire or the total screen 2 of tinned copper wire, count is 80%, outside total screen 2, extrude one deck 125 degree irradiated crosslinking low-smoke and halogen-free flame retardant oversheaths 3.
