Product Details

Company Introduction:

Dehler Technology Co., Ltd. specializes in producing high and low voltage switchgear, box type substation, cable branch box, outdoor vacuum circuit breaker, isolation switch, grounding switch, load switch and low voltage components and other products.

Product Overview:

XBW Power Distribution Prefabricated Substation (European type) is one sealed, moisture-proof and rust-proof double layer structure housing furnished with HV Ring Main Unit (SF6 gas-insulated), instrumental transformer, transformer, LV switch gear, reactive power compensation system, communication system, protective system, UPS power supply and indicating instruments.
It's one outdoor installation integrating primary and secondary side in distribution system. Meanwhile, by using smart components and specific software, it can realize four remote operation smart functions including telemetry, remote communication, remote adjustment, remote control.
This kind of products is suitable for 6 to 35kV ring network and end user. They can be used in industrial zone, residential area, commercial center, park, station, airport, port, oil field, temporary facility and other outdoor area.

Site Environment Condition:

Altitude: No more than 3000m;
Environment temperature: Maximum 40ºC,Lowest -25ºC;
Mean temperature in the hottest month: 30ºC;
Highest annual mean temperature: 20ºC;
Relative humidity: When temperature is 25ºC, relative humidity in air is no more than 95%, monthly mean humidity is no more than 90%;

Structure Features:

With high technology content and reliable performance, 20 years free maintenance;
Function modules standardized assembly; it's a powerful distribution network products; all functions are relatively independent; the user can choose various functional modules according to actual demand.
With high level of automation, CT, PT, protection and communication devices can be installed on the 10kV side. LV can be furnished with the protection and low voltage meter concentrator which can realize the "four remote" of high and low voltage switches and transformers: telemetry, remote communication, remote adjustment and remote control.
The housing adopts double layer, seal and high anti-corrosion structure which is dust-proof, moisture-proof and anti-condensation.
Compact structure, large capacity, small volume.
