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 |
