Abstract

A mouse and ant prevention type low-smoke halogen-free armored control cable with a nylon protective sleeve comprises a plurality of copper conductors (1). A low-smoke halogen-free insulating layer (2) wraps the outer edge of each copper conductor (1) to form an insulating cable core. The insulating cable cores are wrapped by a low-smoke halogen-free inner protective layer (3) after being cabled, wherein one insulating cable core serves as the center, the rest of the insulating cable cores surround the center insulating cable core to form a ring, and a zinc-plated steel belt overlapped armor (4) is added to the outer circle of the ring and then wrapped by the nylon protective sleeve (6). The mouse and ant prevention type low-smoke halogen-free armored control cable is characterized in that a mouse and ant prevention type low-smoke halogen-free protective sleeve (5) is arranged between the zinc-plated steel belt overlapped armor (4) and the nylon protective sleeve (6) in a wrapping mode. The mouse and ant prevention type low-smoke halogen-free armored control cable has the advantages of being capable of preventing mice and ants, free of toxtin, environmentally friendly, and resistant to moisture, oil and corrosion.

Description

Nylon sheath wire rat-and-ant proof type low smoke and zero halogen armoured control cable

Technical field

The present invention relates to the control cables that instructions for use is high, specifically about the armoured control cable of nylon sheath wire rat-and-ant proof type low smoke and zero halogen sheath.

Background technology

At present, the control cables that most of control circuit uses is all that namely copper conductor outer cladding PVC insulate, and protects after core stranding in coated PVC, double-deck zinc-plated steel-tape armouring, more coated PVC oversheath with the insulation of common igelite and jacketed cable.This cable manufacturing process is simple, performance is qualified, so be widely adopted.But this kind control cable adaptive capacity to environment is general, and often have the infringement such as mouse, ant, moisture resistivity, rotproofness are also poor; life-span is not long, if there is burning also can distribute dense black smoke, produces black solid derivative; and discharge the poisonous halogen acid gas of excitant, endanger safety.The derivative that these burnings cause and toxic gas are usually the real arch-criminals of the accident that causes casualties after breaking out of fire.

Along with the development of society, the consciousness of people to safety, environmental protection, fire-fighting and anti-animal pests constantly strengthens, and also improves further the requirement of product.Under this background, devise Novel control cable product, while the work of cable normal power-up, can prevent the harm such as mouse ant, asepsis environment-protecting again, also possesses good moisture resistance, oil resistant, corrosion resistant characteristic, and more wear-resisting, make cable use safer, longer service life.

Summary of the invention

For above problem, the object of the present invention is to provide a kind of armoured control cable of novel nylon sheath wire rat-and-ant proof type low smoke and zero halogen sheath, adopt the low smoke and zero halogen insulating material extrusion cladding of high-quality at conductive surface, protect in coated squash type after core stranding, add the double-deck rat-and-ant proof structure of " armouring+nylon ", namely double-deck galvanized steel strip overlapping armouring, then coated rat-and-ant proof low smoke zero halogen sheath is used, last covered with nylon sheath.

Technical scheme of the present invention is achieved in the following ways: the armoured control cable of nylon sheath wire rat-and-ant proof type low smoke and zero halogen sheath, comprise many copper conductors, the outer rim of every root copper conductor is coated with low smoke and zero halogen insulating barrier becomes insulated wire cores, coated low smoke and zero halogen sheath after insulated wire cores stranding and centered by an insulated wire cores, all the other insulated wire cores form annulus around central insulation core, coated low smoke and zero halogen sheath, the outer ring of sheath installs the overlapping armouring of double-deck galvanized steel strip additional, coated rat-and-ant proof low smoke zero halogen sheath on armouring, covered with nylon sheath again, it is characterized in that: between the overlapping armouring of described galvanized steel strip and nylon sheath wire, be also coated with rat-and-ant proof low smoke zero halogen sheath.

The coated low smoke and zero halogen insulating barrier of squash type is adopted outside described copper conductor.

Many described insulated wire cores twisted synthesizing cables, make cable core sub-circular.

The coated low smoke and zero halogen sheath of squash type outside described insulated core.

Structure of the present invention, adopt the low smoke and zero halogen environmental protection material extrusion cladding of high-quality at copper conductor surface, the control cables produced thus can meet the requirement of International Electrotechnical Commission (IEC) and national cable standard (GB), as insulation resistance, conductor resistance, tensile strength, elongation at break etc., again there is rat-and-ant proof, asepsis environment-protecting, the advantage of moisture resistance, oil resistant, corrosion resistant.Cable has good flame retardant effect, effectively can prevent cable spontaneous combustion or run into naked light time delay afterflame burning, the harmful substance produced and toxic gas also few.Improve the coefficient of safety that cable uses, decrease the degree of property and loss of life or personal injury, extend the useful life of cable.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Known by Fig. 1, the armoured control cable of nylon sheath wire rat-and-ant proof type low smoke and zero halogen sheath, comprise many copper conductors 1, the outer rim of every root copper conductor 1 is coated with low smoke and zero halogen insulating barrier 2 becomes insulated wire cores, and centered by an insulated wire cores, all the other insulated wire cores form annulus around central insulation core, coated low smoke and zero halogen sheath 3 after insulated wire cores stranding, outer ring installs the overlapping armouring 4 of double-deck galvanized steel strip additional, covered with nylon sheath 6 again on the overlapping armouring 4 of galvanized steel strip, rat-and-ant proof low smoke zero halogen sheath 5 is also coated with between the overlapping armouring 4 of described galvanized steel strip and nylon sheath wire 6.The coated low smoke and zero halogen insulating barrier 2 of squash type is adopted outside described copper conductor 1.Many insulated wire cores twisted synthesizing cables, make cable core sub-circular.The coated low smoke and zero halogen sheath 3 of squash type outside insulated core.

Production procedure of the present invention is: 1, insulate operation: adopt the coated environmental-friendly halogen-free low-smoke insulating barrier 2 of squash type to become insulated wire cores outside copper conductor 1.

2, cabling procedure: many insulated wire cores twisted synthesizing cables, make cable core sub-circular.

3, interior nurse's sequence: the coated low smoke and zero halogen sheath 3 of squash type outside cable core.

4, armouring operation: galvanized steel strip overlapping armouring 4 dextrad overlap is put up wrapped.

5, outer jacket operation 1: coated rat-and-ant proof low smoke zero halogen sheath 5 outside the overlapping armouring 4 of galvanized steel strip.

6, outer jacket operation 2: outermost layer covered with nylon sheath 6.
