Our products have a good price advantage and cover most of the South America, Middle East, Africa, and Southeast Asia markets. We look forward to becoming your long-term partner in China.Be it energy supply corporations, industry, or power stations, any owner or user of primary distribution systems for medium voltage places high demands on the switchgear. These include reliable technology, ease of operation, and economy. With our complete range of circuit breaker and switchgear systems for medium-voltage, Siemens sets the standard when it comes to reliable and efficient solutions.

A combined substation (also called a European substation) is a kind of compact and complete set of power distribution units that combine a distribution transformer, HV switchgear, LV switchgear, electric energy metering equipment, and a reactive compensation device in one or several boxes according to fixed wiring schemes. It is widely used in factories, mines, oil fields, airports, highways, residential quarters, underground facilities, and so on.

Combined transformers are suitable for use in substations where space or installation costs make using independent Transformers difficult. Ideal for installation at metering points due to their very high accuracy class, both in current and voltage. Suitable for the discharge of high-voltage lines and capacitor banks.

Whether as resiliency units for fast emergency response or for substation upgrades and refurbishments, trailer-mounted substations are the best choice for temporary use and whenever fast deployment is essential. They provide maximum flexibility and comprise one or several compact modules, e.g., a power transformer, high- or medium-voltage switchgear, cables, control and protection equipment, communication, monitoring, and auxiliary power systems.
