Description
Technical field
The invention belongs to Electric Power Equipment Insulation pipe field, it is related to a kind of Vaccum Permeating sebific duct, particularly a kind of heat-insulated Vaccum Permeating
Sebific duct.
Background technology
Vaccum Permeating sebific duct can only often meet the requirement of insulation as the insulated hull of power transmission line, it is other it is such as corrosion-resistant,
Mechanical resistant impact, fire resisting, heat-insulated performance do not possess.It is understood that electron motion can be slack-off at low ambient temperatures, it can cause
Power transmission efficiency step-down.With the growing tension of the energy, energy-saving and emission-reduction are increasingly valued by the people, and how to be reduced in electricity transmission process
Energy loss and improve power transmission efficiency become particularly urgent.
The content of the invention
It is an object of the invention to provide a kind of heat-insulated Vaccum Permeating sebific duct, the Vaccum Permeating sebific duct can adapt to relatively low temperature
Environment, the heat exchange of power transmission line and outer low temperature environment is effectively completely cut off using polyurethane foam material, it is to avoid Wire temperature is too low,
Electrical energy transportation efficiency is effectively improved, with high use value.
The object of the present invention is achieved like this：A kind of heat-insulated Vaccum Permeating sebific duct, including it is Vaccum Permeating sebific duct, binding agent, poly-
Urethane foaming layer, described Vaccum Permeating sebific duct is hollow pipe, and the outside of described Vaccum Permeating sebific duct sets one layer of polyurethane foam
Layer, is combined together between described polyurethane foaming layer and Vaccum Permeating sebific duct by binding agent.
The thickness of described Vaccum Permeating sebific duct is 3 ~ 6mm.
The thickness of described described polyurethane foaming layer is 10 ~ 15mm.
The thickness of described binding agent is 1 ~ 2mm.
The beneficial effect comprise that：The present invention is provided with a strata in the outside of Vaccum Permeating sebific duct by binding agent
Urethane foaming layer, makes the electric wire in Vaccum Permeating sebific duct not influenceed by outer low temperature environment, and electric wire can keep certain suitable
Temperature, makes power transmission efficiency reach most preferably.
