By using the structure of the utility model, a good protection effect can be played on the cable when there is a fire so that security performance during operation of the cable is good and a usage requirement is satisfied.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to the high temperature-resistant cable structure in a kind of skyscraper low pressure electric line.
Background technology
In skyscraper low pressure electric line, its cable mostly adopts the self cooling branch cable of hollow, it adopts the self cooling mode of hollow that the temperature of cable conductor is obviously reduced, and effectively raises the ampacity of cable, and particularly its ampacity of large tracts of land cable improves more than 1.5 times.Due to the self cooling branch cable of hollow, to have an ampacity large, power supply is reliable, integrated cost is low, quick and easy for installation, the characteristics such as easy to maintenance, but the self cooling branch cable structure of existing hollow is simple, can not carry larger pressure during use, heat resistance is poor simultaneously, thereby the fail safe while making the cable operation is low, can not meet instructions for use.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, and the high temperature-resistant cable structure in a kind of skyscraper low pressure electric line is provided.
The utility model is achieved through the following technical solutions:
High temperature-resistant cable structure in a kind of skyscraper low pressure electric line, it is characterized in that: include conductor, described conductor consists of the many stranded soft copper wire harness that form of copper wire, described conductor is coated with insulating barrier, described insulating barrier is coated with inner restrictive coating, be filled with high-temperature glass fibre rope and energy-saving high-temperature-resistant material between described inner restrictive coating and insulating barrier, described inner restrictive coating is coated with the wrapped thermal insulation layer formed of some polymethyl methacrylate silk ribbons, described thermal insulation layer is coated with by the wrapped heat insulation reinforced layer formed of some inner restrictive coating outsourcing high temperature stainless steel alloy silk ribbons, described heat insulation reinforced layer is wrapped with the armour that adopts galvanized steel strip or aluminum alloy strip establishment, described armour is coated with screen, described screen is coated with the external sheath layer that the poly-hydrocarbon material of modification forms.
Stranded the forming of copper wire that described soft copper wire harness is 0.40mm by 11 diameters.
Described screen adopts two-layer plastic-aluminum combined film winding to form, the wrapped plastic-aluminum combined film of its internal layer, coverage rate 100%; The outer braid tinned wird, shielding density is more than 90%.
The thickness of the external sheath layer of the poly-hydrocarbon material of described modification is 2-3mm.
Described conductor adopts the soft copper wiring harness structure, the copper cash that flexible conductor adopts is thinner, thereby make the hardness of cable smaller, softness is good, be filled with high-temperature glass fibre rope and energy-saving high-temperature-resistant material between described inner restrictive coating and insulating barrier, and, by the structural design of thermal insulation layer and heat insulation reinforced layer, can play a very good protection when the breaking out of fire to cable; And, by the structural design of armour and screen, can increase the intensity of cable, can bear certain pressure.
The utility model has the advantages that:
The utility model reasonable in design, can carry larger pressure during use, and softness is good, and simultaneously heat resistance is good, can play a very good protection when the breaking out of fire to cable, thereby the fail safe while making the cable operation is good, has met instructions for use.
