After several times impact test from 40T to -180T,this wire also can maintain the insulating properties like normal temperat
Insulating layer have very good adhesion with epoxy resin adn polyester resin, Most air conditioning electromagnetic valve coil manufacturers have been using this product, And get very high praise |
Long-term work allowed at temperature 125°C,Short circuit at temperature 250°C,this wire can still maintain normal insulation performance |
After several times impact test from 40°C to -180°C,this wire also can maintain the insulating properties like normal temperature |
