n the last decade the plant of elec-
trotechnical equipment, CJSC
"ZETO" located in Velikie Luki has
been actively working in the fi eld
of integrated supplies to 35-750 kV
power facilities. This approach is fo-
cused directly on customer needs
and is convenient for projects imple-
mentation. It provides a signifi cant
reduction of open switchgear area
and terms for substations design,
construction and commissioning.
The plant produces reliable and
modern products due to the high
standards of production quality con-
trol, cooperation with major manu-
facturers and implementation of the
latest technologies.
Traditionally, CJSC "ZETO" is fo-
cused on the production of high volt-
age equipment. The main equipment
is used in 35-750 kV open switch-
gears. Among the equipment there
are disconnectors, circuit breakers,
earthing switches, surge arrestors,
composite insulators, busbar sup-
ports, rigid busbars, instrument trans-
formers, cubicle switchboards.
The production of gas-fi lled equip-
ment is actively developing. 110,
220 kV SF 6 live tank circuit breakers
(VGT-110 and VGT-220 series), SF-6
dead-tank circuit breakers (VTB-110
and VTB-220 series), instrument
current transformers (TOGF-110-
330-500 and TOGP-500 series),
instrument voltage transformers
(ZNOG-110-220 series) and 110 kV
SF-6 gas insulated switchgear (GIS)
are at the stage of mass production.
Production of current transformer
with nitrogen insulation (TOGF-110
series) has been mastered. The ad-
vantages of afore-mentioned equip-
ment are environmental friendliness
and safety of use.
New types of products are being
developed. The production of cubicle
switchboard based on KM-ORU-110
compact module was laucnhed in
2008. The switchboard is equipped
with domestic production equipment.
"ZETO SMP North-West" (St. Pe-
tersburg), "ZETO SMP Povolzhie"
(Kazan) and "ZETO SMP Siberia"
(Krasnoyarsk) civil construction and
installation departments have been
established to provide a full range
of services for the customers. These
departments are engaged in power
facilities construction and commis-
sioning.
The company considers the im-
plementation of integrated supplies
as the foundation for developing rela-
tions with existing and potential cus-
tomers in the fi eld of electric power
generation, transmission and distri-
bution. Compliance with high quality
control standards at all stages of pro-
duction up to the commissioning of
facilities also contributes to business
development.
110 kV SF-6 GIS produced by
CJSC "ZETO" was certifi ed by an
interdepartmental commission and
recommended for use at facilities
of PJSC "Rosseti" subsidiaries and
affi liates. It was also certifi ed in
the INTERGAZCERT system. The
equipment is included in the Regis-
ter of innovative solutions of PJSC
"Rosseti". Innovative technical solu-
tions for averting the construction of
capital buildings with artifi cially con-
trolled climate provide a possibility to
install GIS outdoors or in unheated
rooms (it corresponds to "U" climate
category with the minimum operating
temperature of minus 45 °С and the
second installation category accord-
ing to GOST 15150). The GIS pro-
duced by CJSC "ZETO" complies
with the requirements of the RF Gov-
ernment Decree no. 719 dated July
17, 2015 and Order of the Ministry of
Industry and Trade no. 3568 dated
November 12, 2015. It is also includ-
ed in the "List of the industrial output
made on the territory of the Russian
Federation". Local manufacturing
content is up to 95%.
