Leskolovo village, Leningrad region

The FULL-CYCLE plant was launched in 2015 in the village of Leskolovo (Leningrad region). It is a key asset of the company. A unique production of Surge Arresters has been created at several production sites:
• A full production cycle: from the preparation of a component mixture for the production of semiconductor varistors to the packaging of finished products of SANp
• A system of 100% control of the output parameters of all products
• Modern equipment and technologies
We produce a wide range of SANp for various voltage classes and operating conditions:
Voltage classes:
• SAN of low voltage classes: 0.4 kV, 0.66 kV, 1 kV
• SAN of medium voltage classes: 3 kV, 6 kV, 10 kV
• SAN of high voltage classes: 35 kV, 110 kV, 150 kV, 220 kV
• SAN of ultra-high voltage classes: 330 kV, 500 kV
Types of execution:
• SAN of the traditional support structure
• SAN of suspended design
• SAN for outdoor installation (UHL1)
• SAN for indoor installation (UHL2)
• SAN in a shortened case
Special versions:
• An SANp with a metal bracket for replacing RVO arresters
• SANp with insulating bracket and separator
• SANp with a separator and a set of fittings for installation on a SIP-3 wire
• SAN for operation in a polluted atmosphere
• SAN of tropical design
Bandwidth classes:
• SAN of the Ith class of throughput
• SAN of the IIIth class of throughput
• SAN of the IVth class of throughput
• SAN of the Vth class of throughput

The company also produces linear arresters of the RVL series for 35-330 kV overhead lines and surge protection devices of the USPN type for overhead lines of 6-20 kV.
