Cable, electrical, foam pipe / Electro-technical equipment

UPTS, a modular integrated transformer substation in concrete cladding with voltage of 6(20)/0.4 kV and power of 100 to 1250 kVA, is used in networks with insulated neutral on the side of 6(20) kV and dead-grounded neutral on the side of 0.4 kV for energy supply to industrial, housing and public, infrastructure facilities, cottage villages and individual dwellings zones.

Feed and outgoing lines are laid by cables. Cable entry is made from the soil through cable facility. If it is necessary to connect UPTS to overhead transmission line (OTL), inserted cable with cross-linked polyethylene insulation and exit to OTL support is used.

UPTS is made as one-transformer substation UPTS, twin-transformer substation (2UPTS) or distribution substation UPTS (UPTS – Unitized Package Transformer Substation in Concrete cladding). Supplied in ready-to-operate units (concrete cladding with equipment). One-transformer substation UPTS is manufactured of concrete claddings of two types:

-left-hand - entry to switchgear bay is located on the left wall of the cladding relative to transformer bay gates;

-right-hand - entry to switchgear bay is located on the right wall of the cladding relative to transformer bay gates;

Twin-transformer UPTS always consists of left hand and right hand units. Twin-transformer version of UPTS with distinguished subscriber part is possible, which provides location of HVPM (High-Voltage package module) and LVPM (Low-Voltage package module) in two different units with individual entries.

After the units are installed, power transformer is installed and connected, HV and LV feed and outgoing cables and external earthing loop are also connected. For twin-transformer UPTS it is necessary to connect HV and LV interbay cable junctions.

By using UPTS it is possible to simplify land allocation procedure and reduce the time of mounting and commissioning of the equipment.

UPTS life is minimum 25 years.

Rated values of climatic environmental factors during UPTS operation as per GOST 15543.1 and GOST 15150:

-ambient temperature is from 60°С below zero up to 40°С above zero;

-relative humidity is up to 100%;

-altitude above sea level is maximum 1000 m;

-environment is not explosive, does not contain current-conducting dust, aggressive gases and fumes in concentrations breaking the materials and insulation, I and II type atmosphere as per GOST 15543.1 and GOST 15150.
