Press Release

UK, County Durham – Thorne & Derrick International

Thorne & Derrick have partnered with Powerstar.

Powerstar are leading manufacturers of LV HV Transformers to enable safe and reliable distribution of Smart Power with online remote monitoring functionality, 600v to 11kV .

The Powerstar SO-LO® range of super low loss Smart Transformers are the only amorphous core transformers designed and manufactured in the UK.

SO-LO® transformers deliver higher energy efficiency, improved distribution reliability and lower power consumption than conventional transformers.

Going Smart

Chris Dodds, Sales and Marketing Manager at Thorne & Derrick, says: “We look forward to developing existing relationships with customers while also presenting the full portfolio of Powerstar transformers up to 11kV to new clients. The ability to provide bespoke smart energy solutions from concept to completion that efficiently manage energy use while lowering electricity consumption and costs is highly attractive. Replacing your site transformer with a low loss amorphous core could reduce core losses by up to 75% when compared to traditional CRGO transformers. Smart Grid is the future.”

The partnership will facilitate knowledge sharing between our two companies and enable us to collaboratively promote the range of fit-for-purpose energy solutions and services available to clients in the utility, renewable and power generation industries.

Dr. Alex Mardapittas, CEO at Powerstar, commented: “We are proud to partner with the renowned and reputable LV HV Electrical Equipment Distributor Thorne & Derrick. The partnership will heighten the visibility of smart transformers and enable a wide variety of organisations to learn how they can modernise their high voltage electrical power infrastructure.”

Smart Power, Smart Transformers – SO-LO transformers ensure real-time and remote asset monitoring to assess performance and operation.

The collaboration will be underpinned by the customer service offered by Thorne & Derrick and Powerstar to support and inform organisations on how they can further improve their LV MV HV infrastructure through customised recommendations such as the implementation of smart transformers that are Industry 4.0 ready.

Thorne & Derrick

Since 1985, Thorne & Derrick International, based in the UK, have been synonymous with the supply and distribution of tested, certified and accredited Electrical Equipment & Cable Accessories by leading manufacturers including ABB, 3M ElectricalNexans EuromoldPfisterer and Prysmian to guarantee the highest levels of reliability for LV MV HV Power Systems.

Press Release: Written by Chris Dodds – Thorne & Derrick Sales & Marketing Manager

Thorne & Derrick have officially partnered with BASEC to promote our shared ambition of providing electrical safety by encouraging industry stakeholders to specify and buy accredited, tested and certified Quality Cables & Cable Accessories.

Here’s Why…..

Last week, a lightning strike triggered a power cut which caused a 5% loss of power to the UK electricity distribution grid.

Such power losses can be a localised nuisance or a national catastrophe and caused by a number of natural or man-made factors: copper theft, fire damage, bird collision, digger damage or issues of Cable Quality.

Cable Quality & Safety

Natural disasters are accidental and inevitable beyond the control of humankind – however Cable Quality can be assured by independent accredited certification bodies for the cable industry at a worldwide level.

Since 1985, Thorne & Derrick International have been synonymous with the supply and distribution of tested, certified and accredited Cable Accessories by leading manufacturers including ABB, 3M Electrical, Nexans Euromold, Pfisterer and Prysmian to guarantee the highest levels of reliability for LV MV HV power systems.

The British Approvals Service for Cables (BASEC) is a recognised sign of assurance of independent cable testing and approval. As an independent body, BASEC has for nearly 40 years been a mark of reassurance to those specifying cable.

“BASEC approached Thorne & Derrick to discuss a potential working partnership – based on the obvious synergies and market positions of both our companies the opportunity to jointly prepare and share highly relevant and impartial technical insights was a natural attraction. Both companies have a passion for and pride in upholding industry standards, specifications and ultimately installations,” comments Harpreet Suree (Marketing Manager at BASEC).

“The BASEC mark gives complete assurance to cable manufacturers, wholesalers, specifiers, purchasers and installers alike,” adds Harpreet.

“Indeed, Thorne & Derrrick working with BASEC will be developing a range of informative resources to achieve our goals – this will include Online Blogs, Case Studies, Meeting Invitations, Seminars, CPD Courses, Training Courses & Online Tutorials. We are privileged to stand shoulder-to-shoulder with BASEC. We would extend this co-operation opportunity to like-minded companies and people sharing a common professional interest. Call us for an informal chat today,” comments Chris Dodds.

Cable Quality is often overlooked when building specification decisions are made, which can result in costly damage and potential loss of life.

BASEC has been in the business of independently testing and certifying cable products and their manufacturing facilities, to internationally recognised standards, for over 45 years.

With a rigorous programme of auditing, inspection and testing their goal is to ensure the cable you specify, source and install is compliant, safe and fit-for-purpose.

The Cable Quality Seminar is designed for anyone and everyone who is working to deliver projects which include cable installations.

Understanding the implications of poor-quality cable and increased awareness of independent cable verification is paramount to your project’s success.

Join us in Milton Keynes to learn how BASEC, recognised instantly in the worldwide cable industry, can help you to be compliant.

Do not miss your opportunity to build your awareness of cable quality.
