Abstract
The utility model discloses a kind of weather resistant drop cable, comprise the first conductor wire core and second conductor wire core parallel with described first conductor wire core, described first conductor wire core outside is coated with the first organosilane crosslinked polyethylene insulation layer, described second conductor wire core outside is coated with the second organosilane crosslinked polyethylene insulation layer, be provided with connecting band between described first organosilane crosslinked polyethylene insulation layer and described second organosilane crosslinked polyethylene insulation layer, described connecting band is made up of organosilane crosslinked polyethylene insulation material.This weather resistant drop cable by tradition two independently insulated electric conductor change two parallel twin-core structures into, plastic extruding machine is once extruded, time saving and energy saving, adopt the black organosilane crosslinked polyethylene insulation with weather-resistant performance, improve useful life, the feature of environmental protection and security against fire.
Description
Technical field
The utility model relates to a kind of weather resistant drop cable.
Background technology
Along with going deep into of upgrading urban and rural power grids, city and country all requires to reach that Every household has an ammeter, and wires and cables industry has welcome again a new opportunity to develop.The low pressure drop cable that China's tradition uses is by two rubber insulation wires or BLV, respectively since backbone is incorporated into user, there is many shortcomings and hidden danger in such drop cable: 1, rubber insulation is registered one's residence after electric wire runs a period of time, drench with rain owing to exposing to the weather, the mechanical electric performance of electric wire reduces greatly, increase power supply department maintenance cost, and bring hidden danger; 2, rubber insulation medium sulphide content and copper conductor produce chemical reaction, generate cuprous sulfide and are corroded, and can make insulation rubber accelerated ageing; Although 3, polyvinyl chloride insulation electric wire of registering one's residence is better than rubber-sheathed wire, as long as Long-term service temperature 70 DEG C, it is anti-aging, weather-resistant property is undesirable; 4, lay inconvenience with two solid wires, waste time and energy, take up room, and unsightly; 5, there is poisonous and harmful smog when rubber, polyvinyl chloride burning, and have a large amount of sour gas to overflow, do not meet environmental protection and security against fire requirement.
Tradition enters registered permanent residence cable so many shortcoming, seriously restricts the demand of the people to electricity consumption growth, environmental protection and security against fire.
Utility model content
For solving the problem of traditional drop cable, the utility model proposes a kind of weather resistant drop cable, this weather resistant drop cable by tradition two independently insulated electric conductor change two parallel twin-core structures into, plastic extruding machine is once extruded, time saving and energy saving, adopt the black organosilane crosslinked polyethylene insulation with weather-resistant performance, improve useful life, the feature of environmental protection and security against fire.
The technical solution of the utility model is achieved in that
A kind of weather resistant drop cable, comprise the first conductor wire core and second conductor wire core parallel with described first conductor wire core, described first conductor wire core outside is coated with the first organosilane crosslinked polyethylene insulation layer, described second conductor wire core outside is coated with the second organosilane crosslinked polyethylene insulation layer, be provided with connecting band between described first organosilane crosslinked polyethylene insulation layer and described second organosilane crosslinked polyethylene insulation layer, described connecting band is made up of organosilane crosslinked polyethylene insulation material.
Further, described first organosilane crosslinked polyethylene insulation layer has outwardly convex ridge or described second organosilane crosslinked polyethylene insulation layer has outwardly convex ridge, and described convex ridge, as phase line index, facilitates ink jet printer for printing product identification.
Further, the width of described connecting band is 1.0mm, and its thickness is 1.6mm.
The beneficial effects of the utility model:
Weather resistant drop cable of the present utility model by tradition two independently insulated electric conductor change two parallel twin-core structures into, plastic extruding machine is once extruded, time saving and energy saving, adopt the black organosilane crosslinked polyethylene insulation with weather-resistant performance, improve useful life, the feature of environmental protection and security against fire.The insulate heat extension property of the utility model weather resistant drop cable is in table 1.
