66kV Jointing Tools
WE LISTENED, SO INTO STOCK….. SHAVE, REMOVE, CHAMFER, & GROOVE
Thorne & Derrick have introduced the Alroc CAMF tools into stock to support customers in the UK & European offshore wind project marketplace. CAMFs are designed purposely for use with 66kV+ XLPE insulated IAC & power cables to provide balanced, consistent and precise cable preparation. CAMFs shave bonded semicon and remove insulation up to 90mm diameter without wobble, struggle or risk to HV cable integrity.

Customised Cable Winch
Working with client NGE, Thorne & Derrick have supplied a custom engineered Telecoms Cable Winch for the pulling and installation of fibre optic cables to the Liverpool Backhaul project – the cable winch will support the high-speed fiber infrastructure project which will connect all 6 local authority areas in the Liverpool Region, by delivering Gigabit internet connectivity to a diversity of key economic activities.
Thorne & Derrick have supplied the AW1000 is an extremely robust piece of engineered plant, designed specifically to cope with Fibre Optic and light cable pulls, which are becoming a mainstay in today’s economic environment, especially as Fibre Optic is being laid to cope with the increasing demand for broadband internet. The Winch is designed and manufactured by SEB International in the UK, to be simplistic in operation, and consequently the client installation team will find the winch is also straightforward to maintain and service.
The result is a product, which is cost effective, and will provide many years of service. The AW1000 will be an excellent investment and addition to the plant fleet of construction companies responsible for the installation and maintenance of fibre optical cabling systems.

Custom Cable Winch for Offshore Cable Pulling Project

This refurbished and customised 5 tonne cable winch was customised to enable the pull and installation of medium/high voltage power cables – the winch was delivered within 2 weeks from receipt of client order. The cable winch enabled the installation of cable runs up to 120 metres from the variable frequency drive (VFD) to the compressor junction box which goes from underground cable trench to above ground and onto the cable containment ladder racking system.
The cable winch modification was based on the standard SEB TW5000 version with additional cable tension dynamometer – the dynamometer continuously checks the cable pulling tension to ensure the forces do not exceed the recommended guidelines.
Cable Pulling Equipment
Thorne & Derrick distribute an extensive range of Cable Pulling & Laying Equipment to enable the safe installation of fibre and copper cables within the telecommunications industry. Safely installed cables reduces operational and maintenance requirements to the network and reduced service interruption to telecom cables, wires, ducts, cabinets and exchanges – products include cable spiking tools, conduit rods, cable lubricant, cable socks and rollers.

Thorne & Derrick are delighted to announce we have been appointed the UK Distributor for the Hand Safety Tool Company range of No Touch Hands Free Tools.
This range of market-leading tools reduce serious hand injuries in the workplace when manoeuvring suspended loads during push-pull operations. To support the introduction of the product range we can provide on-site or online Demonstrations to end-users. There are a diverse range of all-purpose designs that keep hands off and away from potential injury areas and keep workers out of the risk zone. Over recent months our Sales and Marketing Teams have benefited from Product Training with Jim Walts (Director – The Hand Safety Tool Company) and we now have in place stock of their ShoveIt range of tools.
Reducing Risk & Worker Injury
Thorne & Derrick are available and interested to discuss potential applications to improve safe operations in the utility, rail, renewable, oil/gas, port authority, manufacturing and construction industry sectors. The tools mitigate high-risk pushing and pulling operations and associated hand or finger injury – users can guide loads, move and position objects, as well as grab slings and taglines without physically placing hands on the item.
The range of Safety Tools keep your hands off loads enabling “hands-free” lifting – this mitigates the risk of load handling and improves Health & Safety in the workplace.

Matting
Thorne & Derrick are able to arrange manufacture of insulating and switchboard matting from our wide range of premium, low odour, rubber matting to your exact sizes and design and in accordance to IEC61111. Our REACH/PAH/CE approved compliant rubber compounds provide no off gassing which can cause nasty smells within internal environments. Rubber which has a pungent odour usually has been heavily recycled and been manufactured with the use of prohibited chemicals which are banned by REACH/EU. REACH regulations are tightening, and many online reviews of current non regulated matting products found on the market have regular end user complaints of a ‘toxic odour’ and ‘smell’ that does not disappear’. The advice given by the supplier is to ‘clean with soap and water’ or ‘leave outside for a prolonged period’.
The truth is really these products are most probably non-compliant and should not be placed into the European market. Contact us for odour free matting options.

Pre-Commissioning, also known as “Pre-functional Testing,” is an essential step in the installation and implementation of Low & High Voltage Electrical Power Systems – this process ensures that all components and cable accessories of the system are functioning properly and safely before the system is put into operation or “Commissioned“.
High voltage systems are critical to the operation of many industries, including utilities, manufacturing, data centres and commercial buildings. These HV systems are responsible for distributing and transmitting electrical power, and any failure or malfunction can have serious consequences, including injury, property damage, and loss of revenue.
Commissioning is a comprehensive process that involves testing and verifying the performance of all components in a high voltage system. This includes electrical and mechanical components, such as transformers, switchgear, protective devices, and control systems. The commissioning team will also verify that the system meets all safety and technical standards, and ensure that it is properly grounded and bonded.
In addition to ensuring the safety and reliability of the system, pre-commissioning can also identify potential issues and improve the overall performance of the system. This can save time and money by preventing costly repairs, mal-operation and downtime in the future.
Oakes Power Services is a leading provider of commissioning services for Low & High Voltage Electrical Power Systems – their team of experienced professionals have extensive knowledge and expertise in testing and verifying the performance of these systems using the latest tools and technology to ensure that your system is safe and operational
Oakes Power Services provide ongoing support and maintenance to keep LV HV power running smoothly.
By partnering with Oakes Power Services for your commissioning needs, you can have peace of mind knowing that your network is in good hands.
