Description

TSO 126-252-series open distribution devices of block design are used in electrical substations with a voltage of 110-220 kV of three-phase alternating current at a frequency of 50 Hz. We can devise 110-220 kV open distribution devices consisting of various blocks, of both standardized and customized design for a particular facility.

Design:

TSO blocks consist of a metal structure with high-voltage equipment and auxiliary circuit elements mounted on it. The structure is made up of welded frames assembled with bolt connections. The metal structures are manufactured using a protective coating (hot-dip galvanizing), which ensures corrosion resistance throughout the guaranteed service life.

Designations of TSO blocks:

Operating Conditions:

• ambient temperature not exceeding 40 °C (with an average daily calculated temperature not higher than 35 °C) and not lower than 45 °C below zero;
• maximum normative thickness of ice wall at a height of 10 m above ground level is 20 mm with a recurrence of once in 10 years;
• normative wind pressure of 65 kgf/m² (650 N) at a height of up to 15 m above ground level with a recurrence of once in 10 years;
• height above sea level: not more than 1000 m.
