Air Insulated Type Busduct

GENERAL CHARACTERISTICS

It is a busbar duct with air insulation, it composed by standardized or customized modular units in according to customer specification. The casing can be in sheet-steel or aluminum or stainless steel and the bars system in copper or aluminum with segregated phase & non segregated phase both indoor and outdoor type

ELECTRICAL DATA

Rated insulating voltage up toV1000
Rated Current on main bus bars up toA6300
Maximum short-term rated current (1 sec.) up tokA100
Maximum Peak current up tokA230

CONSTRUCTION

The metal case can be made in sheet-steel or in aluminum or in stainless-steel, with all mechanical features necessary to overcome all test foreseen by international standards. The external surface has been treated with protective coating to protect against the corrosion. Usually, the internal surface is painted dull black for facilitated the thermic exchange. Degree of protection up to IP 65 can be ensured for external installation.
The busbars are made of electrolytic copper or aluminum, they can be covered by an insulating materials suitable to stand mechanical, electric and thermic shocks, or painted in dull black in order to facilitate the thermic exchange. The contact surface of the joints can be silver-plated if requested.
The supports for Busbars are in material insulating auto-extinguishing a low toxic-gas emission.

STANDARDS AND TESTS

This complies with the main International standards, all switchboards have passed the relevant tests as per IEC 61439 1 & IEC 61439 2
