Abstract
The utility model discloses a low-smoke halogen-free signal cable for special equipment, which relates to the technical field of cable manufacturing, and in particular to a low-smoke halogen-free signal cable for special equipment. The low-smoke halogen-free signal cable disclosed by the utility model comprises three mutually-twisted insulating wire cores, wherein a belting layer, a cross-linked polyolefin inner sheath layer, a tinned copper wire braided armouring layer and a cross-linked polyolefin outer sheath layer are sequentially arranged at the outer sides of the three twisted insulating wire cores; a filling layer is arranged between the three twisted insulating wire cores and the belting layer; and each insulating wire core comprises a tinned copper conductor, and a cross-linked polyethylene insulating layer is wrapped outside the tinned copper conductors. The low-smoke halogen-free signal cable disclosed by the utility model is simple in structure, good in flame retardance and insulation property, cost-saving, and suitable for being used for large outdoor ship equipment and offshore oil platforms.
Description
Technical field
The utility model relates to the cables manufacturing technical field, particularly the special equipment low-smoke non-bittern signal cable.
Background technology
The special equipment low-smoke non-bittern signal cable, be the auxiliary products of modernization industry construction and special equipment, and the special equipment low-smoke non-bittern signal cable is to belong to one of special equipment cable, along with the improvement of technique and demand and the constantly improvement of properties of product.Special equipment is with low-smoke non-bittern signal cable its strict technological requirement in addition, and materials while producing, recruitment are more, and cost is high, and manufacturing process is outmoded, complicated, loaded down with trivial details, is difficult to meet serviceability and the requirement of special equipment cable.
Summary of the invention
The utility model purpose is for above problem, and a kind of special equipment low-smoke non-bittern signal cable of saving cost, good flame resistance, good insulating is provided.
The utility model comprises three bursts of mutual stranded insulated wire cores, in three bursts of stranded insulated wire cores outsides, sets gradually jacket layer in belting layer, cross-linked polyolefin, tinned copper wire braiding armour and cross-linked polyolefin jacket layer; Between three bursts of stranded insulated wire cores and belting layer, packed layer is set; Per share described insulated wire cores comprises respectively tinned copper conductor, at the crosslinked polyetylene insulated layer of described tinned copper conductor outer wrapping.
The fire resistance of the utility model insulation and sheath material reaches category-A test requirements document in IEC332.3.Cable is had relatively high expectations to the insulation resistance constant, after adopting bilayer to extrude insulation, make insulation resistance constant K i at 20 ℃, 90 ℃ respectively greater than 3000M Ω/km, 3M Ω/km.During according to the burning of the smoke density of designing requirement insulation and sheath material, light transmittance is greater than 70%.When containing sour gas in the product of cable fire, meet water and form acidic materials, the equipment such as electronics, electric and computer are produced the harm such as corrosion, cause secondary to endanger.Therefore the halogen acid gas burst size should be controlled at below 5mg/g during cable fire, to guarantee to reach 1 grade of cable standard requirement.According to the pH value of the emergent gas of designing requirement insulation and sheath material greater than 4.3.The utility model is simple in structure, anti-flammability and good insulating, saving cost, is applicable to outdoor large ship equipment and offshore oil platform and uses.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises three bursts of mutual stranded insulated wire cores 1, sets gradually jacket layer 3 in belting layer 2, cross-linked polyolefin, tinned copper wire braiding armour 4 and cross-linked polyolefin jacket layer 5 in three bursts of stranded insulated wire cores 1 outsides; Between three bursts of stranded insulated wire cores 1 and belting layer 2, packed layer 6 is set; Per share insulated wire cores 1 comprises respectively tinned copper conductor 7, at the crosslinked polyetylene insulated layer 8 of tinned copper conductor 7 outer wrapping.
