RMNS Series Low Voltage Switchgear

Description

General:
Beierbian Group Electric strives to bring our customers the latest technology and competitive power system and best service for transmission and distribution line. The RMNS system are suitable for applications in all fields concerning the generation, distribution and use of electrical energy, e. g., they can be used as: Main and sub-distribution boards for energy and Motor current supply of Motor Control Centers
• Utility companies
• Power plants
• Oil refineries
• Off-shore drilling platforms
• Production facilities
• Buildings for other than dwelling purposes.
The RMNS system is full complied with GB7251.1, IEC 439-1, EN 60 439-1, VDE 0660 part 500, BS 5486 Part 1 and UTE 63-410.

Service environment:
a) Air temperature: Maximum temperature: +40℃; Minimum temperature:-5℃; +35℃ average over 24 hours.
b) Humidity: Monthly average humidity 50% in clear air with the maximum +40℃; Higher relative humidity is permitted in lower temperature. For example, the

relative humidity is 90% for the temperature of +20℃. Variety of temperature should be taken into consideration of moisture.
c) Altitude above sea level: Maximum installation altitude: 2000m or more higher;

Note: Adaption to other ambient temperatures is possible under consideration of the reduction factors. It must be ensured that indoor conditions are maintained for the place of installation. Moisture condensation on the switchgear components must be prevented by suitable measures such as heating and/or ventilation. Installation up to 1000 m above sea level for higher locations the reduction factors has to be taken into consideration.

Extreme conditions:
A suitable surface treatment is applied to ensure tropicalization. With the aid of accessories and strengthened parts the RMNS system meets the safety requirements for earthquake-prone areas.
· in tropical areas
· in earthquake-prone areas
· in shelters
· in shipbuilding
· in offshore switchboards

Note:

1. The current of vertical busbar is extremely up to2000A@+35℃,(+40℃with cooler) .
2. Protection Degree of IP54 is taken into consideration for special design if needed.
