Switchgear SolutionsAutomatic Circuit Reclosers /Sectionalisers

FeaturesIncreased revenue with lower operating costs makes this intelligent switchgear the perfect choice.

From manual sectionalising and single phase protection, up to large scale DSA/SCADA controlled electricity distribution networks and substations, you have the solution for your every overhead medium-voltage need.

Light-weight SolutionsReduced purchasing, installation and operating costs, with intelligent solid-dielectric switchgear.

Offering excellent solid-dielectric insulation in a cost effective solution, U-Series Automatic Circuit Reclosers provide the latest technology in vacuum interrupters, encased in an hydrophobic epoxy resin moulding.

The switching mechanism and switchgear microelectronics are enclosed in a 316 stainless steel tank.

Manual or Automated LBSEasy installation with the choice of manual switching or complete automation.

RL-Series Load Break Switches/Sectionalisers provide a simple low cost solution for your electricity distribution network.

Contained in a hard wearing, SF6 gas-filled, 316 Stainless Steel enclosure is the latest in arc quenching technology Extremely short arcing times (within half a cycle) plus tulip-type contacts with arc-resistant (Cu-W) material ensure a long switching life and extended short circuit making capability.

Current and Voltage transformers molded into the I-side terminal allow easy monitoring for your overhead voltage network, and with optional voltage measurement on the X-side terminal, you have full automation capabilities for your electricity distribution network or substation.

A mechanical lockout and highly visible ON/OFF indicator provide instant visual indication of the switchgear state.

Manual operation is possible using a hookstick, and an innovative design means the switch will trip or close quickly, and safely no mater how fast or slow the switch arm is moved.

The RL-Series LBS is available in bare terminal or fully insulated bushing arrangement, and 15kV, 27kV or 38kVmodels. (rated continuous current - 630A)

Automatic Circuit Reclosers & Sectionalisers

Increased revenue with reduced costs.

A comprehensive range of Medium Voltage Overhead Switchgear gives you complete control of your electricity distribution network with minimal maintenance. Make the Switch!

Low Maintenance up to 38kV

Reduce lost revenue and operating costs, and defer capital works by employing the latest Automatic Circuit Recloser technology.

N-Series Automatic Circuit Reclosers combine state-of-the-art vacuum arc interruption with integrated voltage and current measurement. These features are encased in a fully welded and sealed 316 stainless steel enclosure filled with insulating SF6 gas.

Intelligent Switching

Load and source side voltage measurement and current measurement built in to the N-Series Reclosers, means you can be sure your network is making the right switching decisions in just fractions of a second.

The result is an Automatic Circuit Recloser that provides quick response to faults on your overhead medium voltage distribution network or substation, while reducing maintenance and helping keep outages to a minimum.

The N-Series is available in 15kV, 27kV, & 38kV up to 800A continuous current.

All this ensures you have the latest protection technology in an highly reliable and low maintenance Automatic Circuit Recloser.

Available in 15kV and 27kV models, the U-Series has a rated continuous current of 630A.
