Product Description

ZGS series American prefabricated substation box type Distribution station



Step-up substation is designed as box type and specially for new energy generation industry, which can adjust the low voltage from inverter station to high voltage and then run in power grid. So a box-type inverter station and a step-up station can be integrated into one power generation station. It’s widely applied in Solar Energy Power Plant, Wind Energy Power Plant and Nuclear Power Plant, etc.




1. One of the drafters of the National Standard Mine Flameproof Mobile Substations (GB/T 8286-xxxx ), which will replace the existing national standard (GB/T 8286-2005 ) and it was submitted for trial in Beijing.

2. +20 years experience R&D team, derived from a 60 years of history transformer manufacturer in Changsha, Hunan, China since 1956.

3. Full range of transformer types with customized functions are available.

4. CE & ISO certificated.



Below are the tests conducted by Varelen before delivery. Other tests required by clients can also be done accordingly.

Insulation resistance

Resistance of all windings

Check voltage ratio and vector group

No-load test at rated frequency and rated voltage

Impedance test

Withstand voltage test

Induced over-voltage withstand test

Partial discharge measurement


Product Features

1. Intelligient control, integrated with enclosure, compact structure and high environmental adaptability for outdoor applications.


2. The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel laminations insulated on both sides, guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.


3. Clamping frame: it is processed by CNC cutting, bending and then one-time punch forming, the hole’s size is accurate and the appearance looks delicate.


4. The winding coil is made of oxygen-free copper, class H for main insulation materials and coil is insulated by NOMEX paper of DUPONT brand, LV winding is isolated by copper foils. All these make the heat-resistant is up to 220℃, with excellent overload capacity and low loss, but high efficiency.


5. Varelen practices strictly exclusive casting system of F(155℃) or H(180℃), and the epoxy resin is injected and casted in the vacuum machine, so it’s highly insulated, dust-proof and moisture-proof, which ensures stable and reliable performance
