Product Features
1. The inflatable test transformer is small in size and light in weight (40%-65% lighter than oil-immersed test transformers of the same class);
2. Clean, oil-free, and maintenance-free;
3. Unaffected by harsh weather conditions, and can be tested immediately after on-site handling without needing to rest;
4. Insulation strength is significantly higher than that of oil-immersed test transformers, with minimal corona. (The control section can be customized with overvoltage and overcurrent protection, i.e., dual protection functions)
5. Types: AC, AC/DC, AC series, AC/DC series. Dual overcurrent protection for safer testing.
6. Automatically cuts off voltage output when either high or low voltage current exceeds the set value, reduces voltage to zero, and triggers audible and visual alarms.
7. Safety zero-position detection: Equipped with return-to-zero detection function; further operations can only proceed after confirming zero return, ensuring safety and reliability.
8. Suitable for partial discharge testing: Can be used with a partial discharge-free test transformer as the operating part of a partial discharge system, with system partial discharge less than 5pc.
9. Insulation impedance detection function: Directly reflects the insulation strength of the test object.
0. Strong adaptability: Sophisticated hardware and software anti-interference design, multiple anti-interference methods, adaptable to harsh electromagnetic environments.
Manufacturing Process
1. The product uses a high-voltage bushing formed in one pressing process
2. Horizontal core design effectively improves the product's seismic resistance
3. All products can pass 1.1 times induced voltage withstand test
4. High and low voltage windings use high-strength polyester, oxygen-free copper rod enameled wire
5. The core uses brand new WISCO two-silicon cold-rolled silicon steel sheets
