Abstract
本实用新型公开了一种环保型耐高温电力电缆，包括有三根铜导体，每根铜导体外包覆有低烟无卤聚烯烃绝缘层，包覆有绝缘层的三根铜导体绞合后绕包有耐火层，耐火层外依次包覆有隔离层、铠装层和低烟无卤聚烯烃外护套，耐火层内填充有阻燃物。本实用新型具有优良的耐高温、耐油、耐腐蚀性能，同时采用环保的低烟无卤聚烯烃采用作为外护套和线芯的绝缘层，使得电缆在发生火灾燃烧时不会释放出浓烟和有腐蚀性的气体，有效的保证了电缆的安全性，适应用于对环保要求较高的场所。
The utility model discloses an environment-friendly high-temperature-resistant power cable, which comprises three copper conductors, each copper conductor is coated with a low-smoke halogen-free polyolefin insulation layer, and the three copper conductors coated with the insulation layer are twisted and then wound. It is covered with a refractory layer, and the refractory layer is covered with an isolation layer, an armor layer and a low-smoke halogen-free polyolefin outer sheath in turn, and the refractory layer is filled with flame retardants. The utility model has excellent high temperature resistance, oil resistance and corrosion resistance. At the same time, the environmentally friendly low-smoke and halogen-free polyolefin is used as the insulating layer of the outer sheath and the wire core, so that the cable will not release dense smoke when a fire occurs. And corrosive gas, effectively guarantee the safety of the cable, suitable for places with high environmental protection requirements.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of environment-friendly type thermostable power cable.
Background technology
The conventional electric power cable is to be made up of core and coating and the outer field insulating sleeve layer of core; High temperature resistant, the oil resistant and the decay resistance of this type of cable are all undesirable, and oversheath mostly adopts the insulating material of Halogen to process, when high temperature and fire take place; Not only can produce a large amount of dense smoke; And can produce the very strong poisonous hydrogen halide of corrosivity with " secondary disaster ", jeopardize personnel's life, harm equipment and pollutant atmosphere.Therefore these performances that improve cable seem particularly necessary.
The utility model content
The purpose of the utility model provides a kind of environment-friendly type thermostable power cable, and is not good with high temperature resistant, the oil resistant and the decay resistance that solve power cable in the prior art, and can discharge the problem of dense smoke and corrosive gas during burning.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of environment-friendly type thermostable power cable; It is characterized in that: include three copper conductors; Every copper conductor is coated with the low-smoke halogen-free polyolefin insulating barrier; Be coated with three copper conductors of insulating barrier and be surrounded with flame retardant coating after stranded, said flame retardant coating is coated with separator, armour and low-smoke halogen-free polyolefin oversheath outward successively, is filled with fire-retardant thing in the said flame retardant coating.
Described a kind of environment-friendly type thermostable power cable is characterized in that: said separator is the high molecular polymer separator.
Described a kind of environment-friendly type thermostable power cable is characterized in that: said fire-retardant thing is a glass cord.
The beneficial effect of the utility model is:
The utlity model has good high temperature resistant, oil resistant, decay resistance; Adopt the low-smoke halogen-free polyolefin of environmental protection to adopt insulating barrier simultaneously as oversheath and core; Make cable when breaking out of fire is burnt, can not discharge dense smoke and mordant gas; Effectively guaranteed the fail safe of cable, adapted to and be used for the place higher environmental requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes three copper conductors 1; Every copper conductor 1 is coated with low-smoke halogen-free polyolefin insulating barrier 2; Be coated with three copper conductors 1 of insulating barrier 2 and be surrounded with flame retardant coating 3 after stranded, flame retardant coating 3 is outer to be coated with separator 4, armour 5 and low-smoke halogen-free polyolefin oversheath 6 successively, is filled with fire-retardant thing 7 in the flame retardant coating 3.
