Test heating wire qualified technical standardization standards

Release time:2023-05-05     Click through volume:2260

    Product Introduction

The heating wire is kind of Electric heating material wire, core is made of alloy materials such as nichcr, coppernickel and Constantan as heating conductors. The heating wire is wound on the glass fiber by spiral winding through the processing equipment. Silicone rubber, PVC and Teflon are used as high temperature resistant insulating materials. The appropriate voltage can be selected according to the size of the resistance, thermal effect of the current is used to achieve the purpose of heating ……
