Cheap insulation resistance testers factories in China provide affordable, reliable electrical test equipment used to measure insulation resistance in cables, transformers, and electrical installations. These factories serve manufacturers, wholesalers, OEMs, and custom factories globally, combining cost-efficiency with quality and compliance to international standards.
What is an insulation resistance tester factory?
An insulation resistance tester factory specializes in designing and manufacturing instruments that test the electrical insulation in equipment or systems. These devices apply voltage and measure leakage current to evaluate insulation health, vital for safety and preventing electrical faults. Chinese factories focus on producing budget-friendly testers with durability and accuracy for market competitiveness.
How do cheap insulation resistance testers work?
These testers apply a direct current (DC) voltage, usually ranging from 250V to 10kV, between conductive parts and ground. The device measures the resistance to current leakage through insulation materials, indicating insulation quality. Affordable models balance basic testing functions with essential accuracy and safety features, suitable for both factory and field use.
