Abstract
The utility model provides an environmental-protection control cable of high temperature resistant and fire-resistant. The utility model comprises a tin-coated copper conductor, a lapping and, a sheath, and the utility model is characterized in that it adopts a low-smoke halogen-free irradiation cross-linking polyethylene insulation, a low-smoke halogen-free fire-resistant filling material filling in the clearance between the cable cores, a low-smoke halogen-free fire-resistant belt or a low-smoke halogen-free cushion layer as a lapping, and low-smoke halogen-free polyolefin material or low-smoke halogen-free irradiation cross-linking polyethylene as a sheath. The working temperature of the high temperature resistant conductor is as high as 125 DEG or more than, so the control cable is a cleaning control cable with good fire-retardant and environmental protection properties.
Description
Technical field:
The utility model relates to a kind of control cable, especially a kind of being applicable under the high-temperature work environment, and equipment and instrument relatively precision etc. needs low smoke and zero halogen IXPE insulating environment-friendly cleaning control cable under the environmental protection.
Background technology:
The product of former GB9330 " plastic insulation control cable " regulation; be applicable to occasions uses such as control, monitoring loop and protection circuit; this cable of present most of manufacturer production; working temperature is at 70 degree; not at the cable that requires environmental protection under hot environment; the safety requirements stable performance is safe and reliable under this environment, and the product of former national Specification can not meet the demands far away.The control cable of primary standard regulation has quite serious pollutant sources, and it can produce public hazards such as a large amount of dioxin, lead, halogen when manufacturing, use and waste treatment.Particularly, increased the danger of disaster hidden-trouble and fire owing to the extensive application of electric wire.After breaking out of fire, flame can spread along cable rapidly, and electric wire burning produces a large amount of smog and HCL poisonous gas, and it not only causes people's death by suffocation, the overslaugh fire fighter disaster relief, and modernized electric equipment had great corrosion, cause spot fire.The place more to some modern facilities, the loss of the secondary disaster that fire causes even surpass direct fire damage.So, the fail safe of electric wire and anti-flammability problem, more and more cause people's attention, halide-free low-smoke fireproof cable (also claiming cleaning cable) proposes once more, that is: require electric wire not only to possess fire resistance, do not contain toxic gases such as HCL simultaneously when burning, the smog of generation also should meet the requirement of the standard GA of the Ministry of Public Security 306.1.
Summary of the invention:
The utility model be intended to provide a kind of high temperature resistant conductor working temperature up to more than 125 degree, fire resistance reaches the environment-protecting clean control cable well.
For achieving the above object, the technical solution of the utility model is as follows:
The utility model comprises the tin-coated copper conductor, wrapped and sheath is formed, it is characterized in that: adopt the insulation of low smoke and zero halogen IXPE, low-smoke bittern-free highly fire-proof filler filling cable core gap, low-smoke bittern-free highly fire-proof band or low smoke and zero halogen bed course are wrapped, the sheath of low-smoke halogen-free polyolefin material or low smoke and zero halogen IXPE material.
Be provided with steel band or wire armoring layer in the described control cable, its inner covering is the low smoke and zero halogen material.
Be provided with screen in the described control cable, its screen comprises copper strips lapping layer or copper wire braid.
The utility model overall merit is: 125 degree low smoke and zero halogen IXPE insulation are adopted in insulation, make the working temperature of cable bring up to 125 degree by 70 degree of polyvinyl chloride, cable core is filled and is adopted fire-retardant filler, wrapped low-smoke bittern-free highly fire-proof band during stranding, sheath adopts low-smoke halogen-free polyolefin material or low smoke and zero halogen IXPE protective cover material simultaneously.Low smoke and zero halogen IXPE cable is more wear-resisting than other low-smoke halogen-free polyolefin material softness, has improved the serviceability of cable.Oversheath has also adopted low smoke and zero halogen IXPE material, and is fire-retardant more superior with environmental-protecting performance.Whole cable adopted the low smoke and zero halogen environment-friendly materials, during use and when burning, can not produce harm to environment, belongs to the environmental protection series products, meets the future thrust of cable.The all materials useds of this product do not contain heavy metal element, and the IIA level that product has passed through GA306.1 detects.

1, tin-coated copper conductor; 2, low smoke and zero halogen IXPE insulation; 3, low smoke and zero halogen twining package tape (Fig. 1) or low smoke and zero halogen bed course (Fig. 2); 4, low smoke and zero halogen IXPE sheath; 5, steel-tape armouring (Fig. 2).
Embodiment
The utility model high-flame-resistance environment-friendly control cable, comprise: conductor 1, extrude 2 low smoke and zero halogen cross-linking radiation polyolefin insulations at conductor 1, carry out stranding by insulated wire cores, wrapped low smoke and zero halogen band 3 during stranding is extruded low smoke and zero halogen IXPE sheath 4 at last.Owing in polyethylene insulated cable material, add under the situation of hydrate fire retardant, realize crosslinked by the two keys of beam bombardment polyethylene, material processing performance when extruding is relatively good, so cable is more wear-resisting than other low-smoke halogen-free polyolefin material softness, has improved the serviceability of cable.2 insulation of 125 degree low smoke and zero halogen IXPE are adopted in insulation, make the working temperature of cable bring up to 125 degree by 70 degree of polyvinyl chloride, cable core 1 is filled and is adopted fire-retardant filler, wrapped low-smoke bittern-free highly fire-proof band 3 during stranding, sheath 4 adopts low-smoke halogen-free polyolefin material or low smoke and zero halogen IXPE protective cover material simultaneously.Be provided with steel band or wire armoring layer 5 in the control cable, its inner covering is the low smoke and zero halogen material.Can be provided with screen in the control cable, its screen comprises copper strips lapping layer or copper wire braid.
