Support single-end/dual-end power supply design, power coverage 1kW-30kW, adapt to PID intelligent temperature control (±2℃ accuracy), built-in anti-dry burning, overheating protection and leakage monitoring functions, life ≥80,000 hours. The product is CE, RoHS, UL certified, and can be customized in length, diameter and installation method. It is suitable for industrial ovens, pipeline heating systems and household appliances (air purifiers, heaters).
MOQ：1000PCS
Lead time：25days
Factory location: Zhongshan, Guangdong, China
Resistive Core:
For high-temperature durability, make these from nichrome (NiCr), Kanthal (FeCrAl), or silicon carbide (SiC).
When electricity flows through it, heat is produced.
Protective Sheath:
Insulation made of stainless steel, iron, or ceramic helps to keep water, air, or debris from touching.
Insulation layer:
Ceramic insulation or magnesium oxide (MgO) powder helps retain heat and stop electrical leaking.
