About us

ZWAE provides HV and MV switchgear and continues tradition of Polish apparatus produc-

tion in Lębork.

Our offer is aimed both at power engineering

and industrial plants using power equipment.

Among our customers there are virtually all di-

visions of power concerns in Poland and many

industrial plants. Our apparatus is also sold to

companies from other countries.

The advantage of our company is experienced

and highly qualified personnel who are able to

meet the challenges of modern power engine-

ering. Our products have owned all of the most

important certificates. Besides, our apparatus

have gained recognition among many electrical

power engineering companies, both domestic

and foreign.

Our goal is to become an important partner for

power engineering and industry in the domestic

market. We aim to meet expectations of cu-

stomers, sustaining high quality of offered so-

lutions and prompt completion of works. While

designing switchgear, we strive for keeping it

compatible in terms of assembly with currently

used devices in order to make their exchanging

as simple as it is possible.

You are welcome to visit our website where you

can find detailed information concerning our

company and offered products.
