Product Description

DAYA Prefabricated Combined Transformer Substation Details

A combined substation, commonly referred to as a European substation, represents a compact and integrated power distribution solution. It incorporates a distribution transformer, high-voltage switchgear, low-voltage switchgear, energy metering equipment, and reactive compensation devices within one or several enclosures, following predefined wiring configurations. This comprehensive setup finds extensive applications in various settings, including factories, mines, oil fields, airports, highways, and underground facilities of residential communities.

DAYA Prefabricated Combined Transformer Substation  Parameters


Combined transformers are a practical solution for substations where space limitations or installation costs prohibit the use of independent transformers. They are highly suitable for installation at metering points due to their exceptionally high accuracy in measuring both current and voltage. Moreover, they efficiently discharge high-voltage lines and capacitor banks.

When it comes to resilience units for rapid emergency response, or for substation upgrades and renovations, trailer-mounted substations offer an unparalleled choice for temporary use and expedited deployment. These trailers offer maximum flexibility, consisting of one or several compact modules that include power transformers, high- or medium-voltage switchgear, cables, control and protection equipment, communication systems, monitoring, and auxiliary power systems.

The trailers' external dimensions adhere to local road transportation regulations, and their sturdy base frame safeguards the electrical equipment from mechanical stress during transportation.
