Let’s Meet

Throughout March, Thorne & Derrick continued to invite their supply chain to our offices and we also conducted online meetings to ensure staff are up-to-date with product developments, discuss sales-marketing campaigns and strategy plan for the year ahead.

Thorne & Derrick welcomed Karl McFadden (Commercial Sales Manager at PFISTERER) and Drew Houghton (Commercial Sales at PFISTERER) to our offices for product training including an overview of the market-leading and new generation Sicon brand of stepless shearbolt connectors. Additional manufacturer updates included an impressive presentation on the project award at Seagreen with the SEANEX range of dry pluggable high voltage cable connectors for 66kV inter-cable termination.

Thorne & Derrick hold extensive stocks of the MV-CONNEX separable connector range of inner-cone plug type cable connections for use with 33kV electrical equipment – this is supported by the provision of Jointer Competency Training to ensure the reliability of electrical connections.

Sealing Inter-Array Cables

Working with Orsted, Van Oord and the Inter Array Project Manager from LS Cable & System, Thorne & Derrick have specified a cable sealing system to prevent water ingress into the power and fibre optic cores of de-energised high voltage inter-array cables (IAC).

Manufactured by 3M Electrical their range of EC type Cold Shrink cable end caps will provide protection from exposure to moisture, contamination, corrosion, ozone, UV radiation and other environmental hazards.

The proposed product solution was adopted based upon safe working procedure, field service history and product testing according to ASTM D 412-75: – the Cold Shrink technology cable caps are a flame-free and tool-less installation.

The 3M EC-4 type cap will be applied to protect and seal the exposed power core cable ends following the cable pull-in in general accordance with the installation process outlined in the video below – these will be mounted by the Cable Installation Contractor on the wind turbine foundation and offshore substation (OSS) after removal of excess pull-in lengths.

The fibre-optic cables will be sealed with 3M EC-1 type cap – Scotch 2228 type mastic tape is used to wrap and build-up the diameter of the fibre optic cable where the outer diameter of the FO cables are smaller than 11.6mm. Scotch 2228 is a conformable, self-fusing electrical rubber mastic tape with a strong, temperature stable adhesion for maximum continuous operation up to 90° Celsius.

The Changhua 1 and 2a offshore wind farms will comprise a total of 111 Siemens Gamesa 8 MW turbines. The offshore construction will be carried out during 2021 and 2022, with the project expected to be fully up and running in 2022.

Powering Data Centres

Thorne & Derrick have established an impressive project portfolio across UK, European and US built data centres; supporting the ever-changing industry and modern infrastructure changes with LV-HV Energisation & Electrical Equipment.

This month we supplied cable cleats and management products NTT’s Hemel Hempstead 2 (HH2) Global Data Centre. The HH2 facility provides 6MW of high quality data centre space across 6 data halls – each data hall has its own dedicated plant to a 2N configuration. With 30,000 square feet of net technical capacity, Hemel Hampstead 2 offers excellent connectivity options providing access to multiple carriers and cloud providers. 20kW is possible with high-power rack densities.
