PVC spiral core double-layer heating wire, refrigerator, air conditioner, electric blanket, specialized flexible heating wire

Description :

This product is a PVC spiral core double-layer structure heating wire, designed specifically for household appliances and health care equipment that require flexible heating and stable temperature control. The core adopts high-strength heating alloy wire, which is wrapped around the glass fiber skeleton with precision spiral technology to ensure uniform heat distribution and no local overheating risk; The outer layer is wrapped with food grade or industrial grade PVC insulation sheath, which has excellent electrical insulation, aging resistance, and bending resistance. It can withstand repeated bending without breaking or breaking, and is suitable for dynamic installation environments.

Typical application scenarios include defrosting and heating for household refrigerators, auxiliary heating modules for air conditioning, constant temperature layers for electric blankets, drying systems for electric towel racks, heating elements for foot baths/foot washing tubs, etc. Its soft characteristics make it easy to fit into narrow spaces or curved structures, such as around refrigerator evaporators, inside air conditioning vents, mattress interlayers, etc. It is easy to install and does not affect the overall structural integrity of the equipment. The target users include home appliance manufacturers, HVAC engineering companies, health appliance brands, and OEM factories, especially suitable for bulk procurement scenarios that have comprehensive requirements for safety, durability, and cost-effectiveness.

The product achieves safety redundancy through multi-layer protection design: the inner layer of glass fiber is resistant to high temperature and short circuit, the middle layer of alloy wire is precisely temperature controlled, and the outer layer of PVC is flame retardant, moisture-proof, and wear-resistant, meeting most household appliance safety standards (such as IEC 60335). Support customized length, power density, and connector form to meet different voltage levels (12V/24V/220V) and load requirements. The long-term working temperature range is -20 ℃ to+80 ℃, suitable for various indoor and outdoor climate conditions. It is an ideal flexible heat source solution that replaces traditional rigid heating tubes and carbon crystal films, with high cost-effectiveness and engineering adaptability.
