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 ……

Technical Standard

The heating wire adopts the wire category UL758 as the relevant technical standard, safety regulations for the heating wire can be divided into several sub-categories, such as 3589,3590,3323,3270,1080 and so on. The voltage is divided into two voltage safety levels, 300V and 600V. A heating wire that meets the UL standard must meet the following technologies to fully achieve UL technology Standard, UL company personnel will come to the company every week at random time .
