Products

As the original equipment manufacturer (OEM) for Reyrolle, we are fully committed to supporting the entire Reyrolle installed base at every stage of the product life cycle. However large or small your need, we can offer the most comprehensive and reliable service available for Reyrolle products.

An estimated 250,000 Reyrolle products were manufactured between the early 1900’s to the present day. The combination of outstanding design and build quality means that a relatively high proportion of these units are still in service today.

Operating from Reyrolle’s original site, we offer our customers the best opportunity to achieve the optimum cost effective long term strategy for their existing Reyrolle equipment. See below for further information on our products and services.

High Voltage - Gas Insulated Switchgear: 132kV - 550kV

YG / SPD2 - 132kV - 550kV

Reyrolle YG and SPD2 circuit breakers are suitable for voltages up to 550kV, normal currents of 4000A, and short circuit currents up to 63kA. They incorporate duoblast ‘puffer’ interrupters operating in Sulphur Hexafluoride (SF6) insulating gas. These circuit breakers have been in production since the 1980's and have been installed in the UK, Middle East, Far East and the USA.

We can provide extension, replacement, retrofit, spares, repairs, overhaul and condition assessment of YG/SPD2 type circuit breakers.

YGS - 132kV / 145kV
The Reyrolle YGS gas insulated switchgear circuit breaker has been in production since the 1990's. It comprises of a combination of standard components - circuit breakers, disconnectors, earth switches, current and voltage transformers, busbars, each independently housed in its own earthed three phase enclosure. This modular approach to design permits considerable flexibility in the manufacture of alternative switchgear arrangements to suit all applications.

We can provide extension, replacement, retrofit, spares, repairs, overhaul and condition assessment of YGS type circuit breakers.

High Voltage - Air Insulated Switchgear: 66kV - 550kV

SPL - 66kV - 550kV

Reyrolle has manufactured many variants of SPL type circuit breakers, including from SPL, SPL1, SPL2, SPL2/1A, SPL2C & SPL4. Each are fitted with single or double break SF6 interrupters. They are suitable for indoor or outdoor use with voltages from 66kV - 550kV, normal current up to 4000A and short circuit currents up to 63kA. Exposed insulation is porcelain with shed forms and creepage distances to suit the systems voltages and environment condition.

These circuit breakers have been in production since the 1970's with over 500 installed in the UK, Middle East, Far East, Europe, Caribbean and Africa.

We can provide new, replacement, spares, repairs, overhaul, up-rating and condition assessment of SPL type circuit breakers.

SPM - 145kV

Reyrolle manufactured the SPM circuit breaker during the 1990's with approximtaly 200 units installed in the UK and Far East. The SPM has an open terminal, live tank design and comprises three interrupters mounted on a common mechanism frame. The breakers are suitable for indoor or outdoor use with voltages up to 145kV, continuous currents up to 3150A, and short circuit currents up to 31.5kA. The breaker contacts are driven in both the opening and closing directions by a spring powered mechanism which is common to all three phases.

We can provide new, replacement, spares, repairs, overhaul and condition assessment of SPM type circuit breakers.

L800 / L1000

Types L800T and L1000T single and duplicate busbar metalclad circuit breaker panels were designed in the 1970's, with production ending in the 1990's. During this time, 2000 panels were installed in the UK, Far East, Australasia, Africa, Middle East, Europe and South America.

We can provide extensions, replacement, spares, repairs, overhaul and condition assessment of L800/L1000 type circuit breakers.

L42 / L45

Reyrolle installed over 3000 panels of L42T and L45T during the 1950's to the early 1990's. These were supplied to UK, Middle East, Australia, Far East, Europe, Africa, South America and Caribbean.

We can provide extensions, replacement, spares, repairs, overhaul, up-rating and condition assessment of L42/L45 type circuit breakers.

SMS

During the 1990's up until the early 2000's, Reyrolle manufactured the SMS indoor switch panel.Over 500 units were installed to the UK and Middle East. This 36kV indoor switchpanel incorporates a circuitbreaker using sulphur hexaflouride has for interruption.

We can provide extensions, replacement, spares, repairs, overhaul and condition assessment of SMS type circuit breakers.

Medium Voltage - 3.3 / 11 / 24kV

A, B and C Gear - 11 - 22kV

Reyrolle manufactured C Gear in 1906 and later A and B Gear in the 1930's. Over the years, Reyrolle sold over  60,000 units around the world. Now, over one hundred years on, we can offer customers a retrofit solution for C Gear equipment, which has been specifically designed for customers to seamlessly interface their existing Reyrolle panels replacing outdated oil circuit breaker units with a modern vacuum circuit breaker.

We can provide new, extensions, replacement, retrofitspares, repairs, overhaul, up-rating and condition assessment of A, B and C Gear circuit breakers.

LMT - 11kV

The range of LMT metalclad oil-break switchgear including LMT1, LM23T, LSR, LMT2, LMA, was first introduced in the early 1950's and went on to sell over 100,00 units worldwide. We now offer our customers a retrofit solution which has been developed using all of the Reyrolle application and engineering knowledge acquired since its first development.

We can provide extensions, replacement, retrofitspares, repairs, overhaul and condition assessment of LMT type circuit breakers.
