Combined Type Substation ZBW18-F

ZBW18-F Series of new combined substation is new distribution substation equipment developed by BRLT independently according to American box-type distribution substation products. This product has passed the combined type testing and the identifications of new products.

The design structure completely breaks through domestic conventional design
The high voltage components of high voltage load switch (terminal, ring), plug-in fuses and backup current-limiting fuses are creatively optimized structurally and combined perfectly, placed in immersion oil in the transformer tank. Low-voltage switchgear is also small. The breakthrough of the structure greatly reduces the combined size of the substation, and the area is only 1/3-1/5 of conventional products.

Fully enclosed and insulated structure
The high voltage incoming line is integrated and combined with elbow-type cable plug and high voltage bushing, without exposed high-voltage live parts, so the operation of the product is safe and reliable, and the maintenance is easy.

Meeting the requirements of a variety of low voltage feeder
To meet the different requirements of low voltage feeder, this product is divided into three types. The standard or the enhanced type can be used when the low voltage feeding loop is less, and the integrated type when capacitance compensation is needed for feeder.

Lower Infrastructure Cost
The infrastructure cost is only 1/10-1/20 of the cost of domestic conventional products.

Easy Maintenance At Low Cost
The protection level is IP33DH. The transformer cabinet is exposed to the air, with natural cooling, excellent running condition and without the need of maintenance. All of these advantages can minimum the operation cost

Excellent Transformer Performance
ZBW18-F series dedicated transformer uses oil filling air-gap constant volume principle (equivalent to full-sealed) and cancels the oil conservator, with 20-year free of suspended core. The iron core uses imported high-quality silicon steel. Low voltage foil winding coil is of high mechanical strength, good electrical properties. The innovative design, advanced technology and excellent equipment make the transformer reach the international advanced level, with the outstanding advantages as follows:

Low Loss, Low Noise, Low Temperature Rise
Strong Overload Capability
Good Power Performance
Short Circuit Resistance
High Impact Resistance
