Product Description

Power Supply Safe and Reliable Dry Type Transformer Toroidal Scb10 Scb13 Scb15 Power Transformer High Voltage Power Transformer


Product introduction

Dry-type transformer applies epoxy resin cast process instead of immersing iron core and windings in insulation oil. It consists of iron core made of silicon steel plates and epoxy resin cast coils. Insulation cylinder and other insulators between high and low windings are placed to increase electrical insulation. Its cushion blocks can support and restrain the coils, and its fasteners have anti-loose function. Without using insulation oil, dry-type transformer is fire-proof and explosion-proof, easy to maintain and has high reliability, low partial discharge and long operation life. After vacuum treatment and positive pressure, there is no bubble between turns and layers, and it can greatly reduce the amount of partial discharge. Also, it owns the advanges of small volume, low weight, low noise, high operating efficiency, save room and easy installation. 

Product features

1. The iron core is made of imported high-quality cold-rolled silicon steel sheet.
2. Epoxy resin cast and sealing technique reduces no-load loss, no-load current and noise.
3. Temperature control system and air-cooling system adopts top-blowing cross flow fan, which has the characteristics of low noise, high wind pressure, beautiful look, etc.
4. The adoption of intelligent temperature controller improves the safety and reliability of the transformer.
5. Shell further protects the transformer safety. Options of the protection level are IP20, IP23, etc., and choice of shell material includes but no limited to aluminum alloy, cold-rolled steel plate, stainless steel.
6. The low-voltage outgoing line can be standard bus outgoing, side outgoing and top outgoing. Special customized outgoing way is available.
