Abstract

The utility model relates to a lighting-preventing special measurement and control cable, relating to the technical field of cable manufacture. A grid layer, a total shielding layer, a PE inner jacket and a high flame-retardant halogen free silicone rubber outer sheath are sequentially arranged outside a stranded cable; wherein a dual-layer stainless steel-tape armouring layer and a plurality of drainage wires are arranged between the PE inner jacket and the high flame-retardant halogen free silicone rubber outer sheath; a filling material is arranged between the four strands of mutually stranded cable cores and the grid layer; each strand of cable core comprises four strands of insulated wire cores, and a branch shielding layer is arranged outside the four strands of insulated wire cores; each strand of insulated wire core comprises a conductor, and a fluoroplastic insulating layer is covered outside the conductor. The lighting-preventing special measurement and control cable has the advantages of high flame-retardant property, temperature resistance, resistance to strong magnetic field interference, explosion resistance and lightning prevention, is especially suitable for serious climatic change and specific use places, is capable of normally working and can be effectively protected.

Description

The extraordinary measurement and control cable of anti-thunderbolt

Technical field

The utility model relates to the cables manufacturing technical field.

Background technology

Cable can both the normal transmission signal under harsh climate or special environment for use, detect accurately that data and equipment is not damaged is very important; Because the importance and the fail safe of Measurement and Control System often cause the transmission signals disorder, do not reach the expection result of use because of the cable reason.

Summary of the invention

The purpose of the utility model is to design a kind of high flame retardant, anti-high-intensity magnetic field disturbs, explosion-proof anti-thunderbolt coefficient of safety the is high extraordinary measurement and control cable of anti-thunderbolt.

The utility model comprises four strands of stranded cable cores each other, sets gradually belting layer, total screen, PE sheath and high flame retardant Halogen silicon rubber external sheath layer in the said stranded cable core outside; Between PE sheath and high flame retardant Halogen silicon rubber external sheath layer, double-layer stainless steel steel-tape armouring layer and some drainage threads are set; Between said each other stranded four strands of cable cores and belting layer, inserts is set; Said per share cable core includes four strand insulation cores, outside said four strand insulation cores, sub-shield is set; Said per share insulated wire cores includes conductor, at said conductor outerwrap fluoroplastic insulation layer.

The utility model adopts fluoroplastic insulation and high flame retardant Halogen silicone rubber jacket, heatproof good insulation preformance, asepsis environment-protecting; Adopt the stranded double-deck aluminium-plastic tape of irregular pitch wrapped, the total screen of stranding squeezes PE sheath composite construction, and diamagnetic is disturbed; Adopt shielding multipoint earthing and double-layer stainless steel steel-tape armouring and attach many copper conductors, drainage effect is good, has superpower anti-thunderbolt function, has guaranteed that effectively cable is in abominable natural calamity and special environment occasion safe handling property.

The utlity model has high flame retardant, heatproof, the interference of anti-high-intensity magnetic field, explosion-proof anti-thunderbolt, be specially adapted to harsh climate and change and special field of employment, equipment can operate as normal also can be effectively protected.
