Product Description

ZGS-12/0.4 Power Transmission And Distribution Prefabricated Compact Package Unit Transformer Substation

ZGS series pre-installed box-type substation (American type) is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as substation, metering, compensation control and protection devices.

This product meets the following standards:

GB/T17467-1998 "high pressure low pressure preinstalled type transformer substation"

DL/T537-93 order 6 to 35 kv box substation technical conditions"

Conditions of use

ASL not exceeding 1000m;

Ambient temperature: - 35 ºC ~ + 40 ºC;

Relative humidity: day average no greater than 95%, the monthly average no greater than 90%;

Mounting ambicnt: no fire and explosion danger, chemical corrosive gas and well ventilated place, the ground tilt Angle is not more than 3 °.

Function and characteristics

Fully insulated, fully sealed, free or less of maintenance and reliable to ensure personal safety;

Compact structure, with the volume being only 1/3-1/5 of European transformer with the same capacity, and low height;

Adopting box-type structure to avoid oil pollution in the transformer oil tank; adopting double fuses on the HV side for full range protection, thus greatly reducing the cost;

Able to be used as ring net or terminal and the cable head can be plugged and unplugged in case of 200A load current;

Adopting honeycomb double sandwich composite board for the box, thus endowing functions of temperature isolation and heat dissipation;

Equipping electronic phase-loss protector on the LV side to quickly disconnect the main switch when abnormal voltage occurs in the system;

Equipping oil-immersed load switch or SF6 load switch which can be electrically upgraded on the HV side, thus to lay a foundation for the automation of distribution network;

Adopting oil-immersed S9 or S11 series transformer with better performance.
