After 3000 hours of accelerated aging testing at 155°C, HAIPART enameled wire demonstrated an insulation resistance degradation rate of less than 5%, far exceeding the industry average of 20%. This stability enables RCCBs to maintain maintenance-free operation for 20 years in tropical climates or enclosed distribution cabinets.
Applications:
✅Household RCCB zero-sequence current transformers
✅Industrial RCBO latching relays
✅DC leakage detection modules for new energy protectors
FAQ
Q1:What are the reasons for severe overheating of wires?
A1:The load current exceeds the rated value, the wire resistance is too high, and the ambient temperature is too high.
Q2:What is the source of the abnormal noise from the wire?
A2:Wire vibration, poor contact, electromagnetic interference.
Q3:What are the typical symptoms of a damaged wire?
A3:Insulation layer cracking, localized overheating, short circuit tripping, and oxidation and discoloration of the connectors.
Q4:Can the wire be used again after it burns out?
A4:Use is strictly prohibited. Burning will cause insulation failure, which can easily lead to short circuits or fires.
Q5:What are the common causes of excessive temperature rise in conductors?
A5:Overload, excessive contact resistance, poor heat dissipation in a confined environment.
Q6:How to reduce electromagnetic interference from wires?
A6:Use shielded cables, optimize wiring paths, and add ferrite cores if necessary.
Q7:What factors affect the lifespan of a conductor?
A7:Load fluctuations, environmental corrosion, and mechanical damage.
Q8:What are the prices of your products?
A8:Product prices vary depending on the model, specifications, and quantity. Please consult the sales team or check the official website for details.
Q9:What after-sales services do you provide?
A9:We provide comprehensive after-sales services, including product consultation, technical guidance, installation and commissioning, repair and replacement, and warranty.
Q10:How can I contact your technical support?
A10:Technical support can be contacted through the official website, customer service hotline, or email.
