Product Introduction

MOEORW-WSY11 power frequency withstand voltage test complete set is an upgraded generation product optimized on the basis of traditional TDM test transformers, matched with a supporting 5kVA test control box. The whole equipment is used for AC/DC high voltage withstand tests of electrical products.

The test transformer adopts multi-layer separated oil duct insulation structure, solves the oil leakage defect of old TDM models, and the top casing of the sleeve acts as an oil storage tank. Equipped with a special control box with voltage regulation, real-time monitoring and multiple safety protection, the equipment features compact size and light weight.

Strict high-voltage safety design is adopted; only qualified professional technicians are allowed to operate. Reliable grounding is mandatory during the whole test process to avoid electric shock and equipment breakdown risks.
