Low-voltage

• 

Low-voltage switchgear (РУ) according to the technology SIVACON 8PT designed by:

• Input distribution devices of:
  
  • electrical energy input
  • electric power distribution
  • energy accounting
• main distribution switchgears
• low voltage electrical switchboards
• low-voltage switchgears
• supporting distributing devices
• automatic circuit breaker cabinets
• Sectional Cabinets
• reactive power compensation installation
• Motor control centres (MCC)

SIVACON had passed the following tests in  standards compliance - IEC 60439-1, DIN EN 60439-1 (VDE 0660 part 500):

• test for temperature limit;
• insulation resistance check;
• closed-circuit fault tolerance check;
• test for correct wiring between the combination bodies of switching devices and the grounding conductor according to the results of the resistance check or measuring;
• check for closed-circuit fault tolerance of the grounding conductor;
• check of creepage distances and air gaps;
• mechanical integrity testing;
• IP protection level testing.

Every power distribution device SIVACON passes the following types of testing before shipping:

• a visual monitoring of production, including wiring works, and functional tests on electrical equipment if required;
• insulation resistance check;
• check of protective measures and visual monitoring of the end to end ground lines.

In the SIVACON system safety requirements are maintained by the range of the following factors:

• error prevention in the maintanance in the draw-out type switch cabinets due to the fine adjustment of the mechanical guides and appliance of the block systems;
• appliance of the only limited range of the high quality insulation materials (eg: for bus holders, stiffening plates etc.);
• appliance of the reliable switching devices designed by Siemens assures a long-term operation and reduces downtime;
• a reliable shutdown after 70-100 msec even by a long delay time due to th power automatic circuit-breakers 3WL with a control of selectivity (ZSS);
• automated design assures the right choice and equipment allocation;
• check of the system for the localization capability;
• availability of the quality management system.

Modular low-voltage power distribution products – a standard solution for a range of branches of industry:

• electric power stations;
• distribution cabinets for buildings and structures;
• distribution substations;
• main distribution boards and secondary elctrical power systems for energetics, chemical, petroleum, gas industry and other branches.
