Copper Earth Bars for Lightning Protection Systems

Earth bars are an integral part of an Electrical oBuilding Services or Substation technical specification for earthing and bonding; they provide a convenient common earth point for the infrastructure. It is critical copper earth bars provide long lasting, high quality earthing capable of enduring any potential dangerous fault currents.

Main earthing bars provide a recognised earth connection/ reference point and allow the local substation earth resistance to be measured using a clamp meter.

Thorne & Derrick and AN Wallis are aware of the crucial role of an Earth Bar which is why they manufacture high quality, affordable earth bars that are designed and tested to all relevant standards – manufactured from hard drawn copper bar to BS EN 13601 and tested to BS EN 62561-1 Class H.

Earthing bars can be tinned and bases powder coated to improve corrosion resistance
Bars are pre-drilled with cable connection holes with optional threads for installation ease
Manufactured from highest conductivity and quality copper to British Standards
Full range of standard, single and twin link types for LV, MV & HV switchroom/substations
Customised to suit the earthing requirements of your project on short lead times

Compact Lightweight Multi-adjustable Laser Scanner

“The Topcon GLS-2000 series laser scanner we used within the 132kV substation was the Topcon GLS-2000M – the GLS-200 series is composed of 3 comparable, yet distinct models: the GLS-2000S (short-range), GLS-2000M (middle-range), and the GLS-2000L (long-range),” explains Richard Shepherd, MD at Utility & Transmission Survey Solutions Ltd.

Topcon laser scanner is a full featured scanner that can be effectively used to capture existing, as-built conditions for any application range. The compact, lightweight series of scanners accurately captures a full 360° scan including images in less than three minutes.

Selectable laser modes Class 3R to Class 1M
Multiple lens array system – quickly switches focal length settings
Auto temperature adjustment – consistent accuracy throughout the work day
Precision – signal processing wave form for the ultimate in precise data

PR : Topcon Positioning Group announces the release of three new models to the GLS line of laser scanners — the GLS-2000S, GLS-2000M and the GLS-2000L.

The scanners are designed to capture data based on the measurement range needs of specific applications.

“These new GLS-2000 scanners offer purposeful solutions and versatility that comes from the multiple measurement modes with each model,” said Charles Rihner, Vice President for the Topcon GeoPositioning Solutions Group. “The S model is optimized for short-range applications, while the M and L models are perfect for medium and long-range measurement fields, respectively.”

Using Topcon Precise Scan Technology II, the GLS-2000 models are designed to emit pulse signals three times faster than earlier GLS systems. “Using faster pulse signals enables timing to be detected more precisely, which results in reduced noise and higher-accuracy data,” said Rihner.

Additionally, the systems feature dual 5MP cameras, including one with a 170-degree wide-angle lens for high-speed imaging, as well as an 8.9-degree telephoto camera that is coaxial with the measuring axis.

When paired with Topcon ScanMaster software, the models provide complete systems for capturing and processing 3D point cloud data.

Modern-day cable jointers utilise a broad range of Cable Jointing Tools to ensure precision accuracy and clean removal of cable sheath, cable insulation, semi-conductive screens and core preparation. This picture shows the cable jointer using Intercable cable stripping tools to remove the XLPE insulation from medium voltage power cables to enable application of the cable termination.
