ZGS11-200~1000
ZGS11-200~1000

ZGS11-200~1000 three phase combined transformer  

 

Production introduction

1. ZGS 11 combined transformer is one of the high-tech products developed by our company on the basis of pad-mounted

transformer.
2. Range of capacity: 200-1000KVA. The product is suitable for the neutral-point insulation system or small-resistance grounding
system in a 10KV/11KV distribution network, or neutral-point solid grounding system of a three-phase four-wire system in a
400V distribution network.
3. Excellent design, reliable distribution, compact structure, light in weight, and low noise, etc; it has two types of cable outlets:
ring net type and terminal type.
4. The product can be placed directly into the load center of 10KV/11KV network, thus the line loss is reduced and power
distribution reliability is increased.

 

Performance characteristics
1. The ZGS11 combined transformer consists of high-voltage and low-voltage chambers and transformer tank in the operation chambers.
2. H.V. incoming lines in 10KV/11KV cross-linked cables are connected to load switch through knuckle connectors, straight plugs and sleeve sockets.
3. On the high-voltage side, a protection of double fuses (backup current-limiting fuse and plug-in type of fuse are used.
4. There are terminal type and ring net type high-voltage load switches for selection.They are easy to connect, convert and reliable for power supply.
5. In the low-voltage chamber, a fixed type or drawable type is optional for the low-voltage switch cabinet according to user's requirement. Various low-voltage apparatus, such as metering and protection instruments are available. (Note: In general they are customized)
6. The oil tank is fully-sealed by corrugated radiators, which features compact and superior appearance.
