Saudi Lucy is capable of producing wide range of Ring Main Units (RMUs) in Oil and SF6 medium,Overhead load break switches,fuse cutouts,disconnector,Sourcing Earth Fault Indicator in the Kingdom of Saudi Arabia.

Ring Main Units can be classified on the basis of medium use inside the units.Oil RMUs are replaced by the modern SF6 and Vacuum dielectric medium.Even though still Saudi Lucy has a lot of orders for the Oil Type.Since it is the cheapest and robust model.

Automation of RMU are vital for the Electricity Board to reduce overall cost of maintenance,man intervention,time consumption to clear the fault,remote monitoring,isolation of network.Saudi Lucy provides a vital role and research for providing new technology and method to the countries Electrical company.

Here are the classification of Saudi Lucy’s products based on our customer point of view

What is Ring Main Units(RMUs)?

Distribution networks are normally formed by interconnecting a number of ring shaped grids. Distribution transformers are then connected to the system by T-offs. Instead of specifying and selecting individual components required for a T-off, the required components are frequently available in an integrated package known as a ring-main unit (RMU).

Ring-main units normally consist of switches on both sides of the T-off, one to open the ring and another at the connection to the distribution transformer using one of the following:

  • Switch and a fuse separately
  • Switch-fuse combination
  • Circuit breaker   

The earthing switch of the transformer is also usually integrated into the RMU. Each component must first be certified to the IEC Standard applicable to that component.

To insure the safety of the overall design, internal arcing tests performed according to IEC 62271-200.

 

 

Ground Mounted Secondary Switchgear

 

AEGIS

 

The latest design from Lucy Switchgear & Saudi Lucy, the “AEGIS” is a panel style ring main unit designed for front  entry cabling. Available for indoor type secondary distribution applications. Utilizing vacuum circuit breakers,  “AEGIS” has been designed for long service life and virtually zero maintenance.

 

Sabre RMU

The Sabre ring main unit range includes fully extensible and non-extensible options, providing the full  range  of  solutions  required  for  a  secondary  distribution  system.  The  equipment  is  fully weatherproof  for  outdoor  use,  incorporates  vacuum  circuit  breaker  technology  and  has  been designed for long service life with virtually zero maintenance.

 

Trident FRMU

The Trident range of oil insulated extensible and non-extensible ring main units has been developed over  a number  of  years  and is  a leading  performer  in  the  global  market. For  both  rural and industrial applications, this equipment, incorporating HV fuse protection, can be positioned in the most extreme of outdoor conditions with ambient temperatures from -10ºC to 55ºC.

 

HV Metering Units

For HV (High Voltage) metering applications, the AMU (Air Insulated Metering Unit) is designed for use with the  latest Sabre VRN2a (250A) and VRN6a (400/630A) Ring Main Units, but is also compatible with the full Sabre RMU family, including the extensible units.

Switchgear Automation

Gemini- Remote Terminal Unit 2

The G2-RTU has been specifically designed for the control and monitoring of both ground and pole mounted MV (Medium Voltage) switchgear. This highly versatile interface is based on an open and modular  architecture,  supporting  different  communication  protocols  and  media  and  includes advanced features such as battery monitoring and integral FPI (Fault Passage Indicator) to name a few.

 

Gemini-DC

The  Gemini-DC  is  a  stand  alone  device  acting  as  a  SCADA  (Supervisory  Control  and  Data Acquisition)  front   end  processor  and  performing  key  functions  such  as  data  capture  and monitoring,  simple  control  of  serial   ports,  protocol  conversion  and  data  consolidation  for transmission over Ethernet.
