ZGS Series Combined Transformer (American Box Transformer) Overload
Capacity
Description:
ZGS series combined transformers are American box transformers
produced by our company. As an important power supply unit in the
cable distribution network, this product is widely used in urban
and rural distribution networks. It integrates high voltage
control, protection, substation and distribution equipment.
High-voltage load switch and high-voltage fuse are placed in
transformer oil. Fully sealed structure with oil temperature meter,
oil level gauge, pressure release valve, oil release valve and
other components to monitor the operation of the transformer, the
product is divided into ring network type, terminal type and dual
power supply mode. In order to adapt this product to the practical
requirements of power grid, HJATIS has introduced the plug and pull
type dry fuse. The fuse of the fuse does not affect the performance
of transformer oil. According to the complexity of low pressure
feed out, HJATIS ZBW products can be divided into three types:
standard, reinforced and integrated, which makes the user design
units more flexible and economical.

Note: when ordering this product in excess of the above conditions,
you can negotiate with us.
Feature:
Compact structure and small size. It is only about 1 / 3 / 1 / 5 of
the change of the domestic European box of the same capacity, which
greatly reduces the area occupied.
Fully sealed, fully insulated structure, no insulation distance,
reliable protection of personal safety.
Transformer performance excellent low-voltage loss, low-temperature
rise, overload capacity, short-circuit resistance, strong impact
resistance.
Meet all kinds of low voltage feed out requirements, can be
selected according to the scheme, can also be designed by itself.
There are 200A elbow plug and 600a "r" fixed cable connector at the
cable head, which can be equipped with fully insulated zinc oxide
arrester isolator.
