Friction destruction.
Again, uniformly brush one layer of silicone oil in the outside of bus insulation layer:First silicone oil thermal conductivity is good, and bus can be made exhausted
The aerial cooling of edge layer is more uniformly distributed;Second silicone oil good in oxidation resistance, can protect the higher bus of freshly extruded temperature exhausted
Edge layer is not oxidized in atmosphere;3rd silicone oil lubricity is good, and freshly extruded not completely crued bus insulation layer can be made to reduce
With the friction of contact, thus be conducive to improve bus insulation layer surface smoothness;4th silicone oil has hydrophobicity feature, makes
Can be quick by way of the silicone oil of bus insulation layer surface is scraped after bus insulation layer water-cooled in putting into bosh
Ground eliminating water, thus the technique such as need not dry, drying can accelerate the aging of bus insulation layer and high energy consumption, efficiency are low.
Finally, heat conductive silica gel is made to be full of the gap that in heating bus group, each invariable power generates heat between bus, such that it is able to carry
High-heat conductive efficency, such that it is able to make heat be dispersed into more quickly in the surrounding air needing heating, improves tandem type perseverance work(
The efficiency of heating surface of rate ribbon heater;And so that heat is more uniformly spread, it is to avoid the excessive material aging causing of local pyrexia amount is even
Cause the accidents such as short circuit and fire hazard.
