Abstract

The utility model relates to a cable wire, in particular to a fire-resisting cable, consisting of a conductor, a fire-resisting mica, cross-linked polyethylene insulating layers, halogen-free flame-retardant wrapping belts, mineral filling ropes and a low-smoke halogen-free flame-retardant sheath. The fire-resisting cable is characterized in that the mineral filling ropes are filled among the cross-linked polyethylene insulating layers, the halogen-free flame-retardant wrapping belts are filled among the cross-linked polyethylene insulating layers and the halogen-free flame-retardant wrapping belts, the core position of the flame-retardant fire-resisting cable is a conductor, and the fire-resisting mica wraps on the conductor and is extruded by the cross-linked polyethylene insulating layers. The fire-resisting cable has the advantages that the extensibility is higher, the smoke is low, the toxicity is low and the flame retardance and the fire resistance are achieved.

Description

Fire-resisting cable
Technical field
The utility model relates to cable and wire, particularly a kind of fire-resisting cable.
Background technology
China's flame-retardant electric wire and cable product is fire-retardant with Halogen to serve as that main this electric wire discharges a large amount of dense smoke and corrosivity halide and causes casualties and corrode various device so-called " secondary disaster " when burning.For reaching the exploitation that many producers inside and outside low cigarette, low toxicity and the fire-retardant country of destination all are devoted to halogen-free low-smoke flame retardant material.The amount of being fuming discharges toxic gas less and reduces injury to human body and instrument and equipment less during this class material combustion.Developed countries compares early the research of low-smoke halogen-free flame-retardant electric wire and cable material, and technology is ripe, enters the practical stage now.
Summary of the invention
The purpose of this utility model is to provide a kind of low cigarette, Halogen, fire-retardant and fire-resistant cable, has higher extension, low cigarette, low toxicity, anti-flammability and fire resistance.
The utility model is by the following technical solutions:
Fire-resisting cable, form by conductor, fire-resistant mica, crosslinked polyetylene insulated, halogen-free flameproof band, mineral-filled rope, low-smoke halogen-free flame-retardant sheath, it is characterized in that: fill with mineral-filled rope between crosslinked polyetylene insulated and crosslinked polyetylene insulated, fill by the halogen-free flameproof band between the crosslinked polyetylene insulated and low-smoke halogen-free flame-retardant sheath, the most crucial place of flame resistant cable is a conductor, fire-resistant mica is coated on this conductor, crosslinked polyetylene insulated being extruded on the fire-resistant mica.
The material of low-smoke halogen-free flame-retardant sheath is compound halogen-free low-smoke flame retardant material.
Crosslinked polyetylene insulated layer has anti-various chemical solvent, and is more stable in the various around corrosivity mediums; The external diameter of cross-linked polyethylene insulated cable is littler than the full polyvinyl chloride cable external diameter in specification of the same race cross section, can reduce to use caliber in the poling construction, or wear more cables under same caliber condition, reduces the construction and installation cost; The cross-linked polyethylene insulated cable product is gently more many than the weight of polyvinyl chloride cable product, and the installation and transportation of being more convenient for reduce labour intensity, reduce freight; The maximum amount fixed temperature can reach 90 ℃ during the cross-linked polyethylene insulated cable long-term work, and the maximum temperature of cable conductor can reach 250 ℃ during short circuit, and ampacity is greater than polyvinyl chloride cable; Do not discharge corrosive gas and toxic gas during burning, can not produce secondary harm, meet modern security against fire requirement.
Fill with mineral-filled rope between crosslinked polyetylene insulated and crosslinked polyetylene insulated, have well heat insulation, flame retardant effect.
Low-smoke halogen-free flame-retardant sheath is made of the LSZH fire proofing, has excellent mechanical and physical performance, and environmental stress cracking resistance is good, and good resistance to wear is arranged, and more can bear concentrated mechanical stress than PVC and PE, has more effectively protected the cable inner core.
