Detailed introduction

S9-M 10KV oil transformer manufacturer

S9-M 10KV Oil Type High Voltage Transformer

Structure Characteristics:
S9-M 10kv oil immersed distribution transformers are widely used for power supply & distribution in industrial and civil occasions, to step down grid voltage (11, 10.5, 10, 6.3, 6KV) to line voltage 400, which can serve both indoors and outdoors at an ambient temperature range -25℃ to 40℃. With reasonable structure design, the transformers are qualified to withstand short-circuit and overload, and are free of maintenance and easy to repair.
The transformers have S9 and advanced S11 series, the S11 is more recommended for less loss of both load and no-load.
