Stokbord®Drum | 33kV Cable Protection for Underground Medium Voltage Cables
May 4th, 2021
Centriforce Stokbord® Drum has been installed as part of SSE’s improvement programme
Stokbord® Drum By Centriforce
Protection of High Voltage Electricity Cables
Centriforce, working through their distributor network including Thorne & Derrick, last year announced a new cable protection product that can help to improve working safety for High Voltage Electricity Cables applications – known as the Stokbord® Drum.
Centriforce are pleased to share that Stokbord® Drum has been installed as part of SSE’s improvement programme Petersfield – Fernhurst Network Upgrade.

The multinational energy company SSE has launched a network upgrade programme set to future-proof the local electricity infrastructure for homes and businesses of Petersfield, Fernhurst and the surrounding areas.
Through cable network upgrades and the refurbishment of an established substation, SSE’s work will prepare the network for future commercial and residential connections.
Born from our policy for innovation and continuous improvement, Stokbord® Drum is a faster and safer alternative to traditional buried cable and pipeline protection. Stokbord® Drum is a single material strip supplied on an industrial reel which, to install, is simply unwound into the trench removing the need for operatives to set foot below ground.
Suitable for high impact protection against heavy-duty tooling and machinery, Centriforce manufactures Stokbord® Drum to the same industry standards as our globally trusted Stokbord® Cover. The installation time and cost benefits gained through this innovation makes Stokbord® Drum the perfect partner for large scale utility projects.

An excellent example of Stokbord® Drum’s project versatility

Stokbord® Drum has also been installed on major infrastructure projects including: Triton Knoll, Hornsea 2, Dogger Bank
Key benefits of Stokbord Drum
Stokbord® Drum offers a range of key benefits to constructors and end-users including:
- Time and cost saving – Stokbord® Drum significantly reduces installation time in comparison to traditional cable protection, up to 5x faster than alternatives
- Reduced Risk – Helps to reduce potential risks posed to operatives by reducing the need to enter the trench
- Industry Specifications – Stokbord Drum complies with all UK and international industry specifications
- High impact resistance – Meets the same standards as Stokbord® Cable Cover – Stokbord® Drum does not shatter on impact from heavy-duty tooling and machinery
- Highly visible – Stokbord® Drum uses bright colours and bold text to provide a clear visual warning to workers and excavators on-site
- Long-lasting – Rot resistant and chemically inert to ensure the product’s long service life

BAND-IT Band Clamps Used In TR-343 Transducer Assembly
May 4th, 2021
BAND-IT ULTRA-LOK Alloy 625 Clamps
Secure Rubber Boot on TR-343 Transducer Elements
A key component of sonar systems for surface military vessels is the AN/SQS-53C Sonar array, made up of 576 TR-343 Transducers, the array is located in the “bulb” on the bow just below the water surface. Each of those transducers contains a rubber boot or sleeve secured with an ULTRA-LOK Alloy 625 band.
BAND-IT IDENTIFIED AS ONLY SOURCE
During the sourcing process, the US Navy identified BAND-IT as the only responsible source capable of providing the required supplies. Citing the potential for delays and unrecovered costs, the agency chose BAND-IT as the only approved manufacturer based on performance and testing requirements of the Critical Item Production Fabrication Specifications (CIPFS) for the Transducer.

BAND-IT BAND-FAST Clamps Used In EJP Electric Submersible Pumping Systems

BAND-IT BAND-FAST
Precut BAND-FAST Clamps Delivers Performance & Value
In EJP Electric Submersible Pumping Systems
Epsindo Jaya Pratama (EJP) is a company that values quality.
If you visit EJP’s website, you will see a section that describes the standards they maintain for the pumping systems they produce, and the customer experience they promise. But like every business, they also are cost-conscious. The drive to cut costs for manufacturing their Electric Submersible Pumping (ESP) System compelled EJP to switch from BAND-IT fasteners to a competitor’s range of cable ties, a decision they soon reconsidered.
MONEY FLOWS WHEN OIL FLOWS
Subsea downhole oil extraction is different from convention drilling in the oil and gas industry because most of the energy required to transport the produced fluid is supplied by mechanical means rather than by reservoir pressure. That puts more “pressure” on ESP systems. Any time the system needs maintenance or repair, production is interrupted, and the well isn’t generating oil or revenue.
➡ BAND-FAST is part of a full line of products that have achieved the highest level of quality certification ISO 14001:2004 | ISO 9001:2008 | IATF 16949


BAND-IT XE4809 Fromm Pneumatic Combination Banding Tool
BAND-IT BAND-FAST Stainless Steel Clamps
EJP’s customers expect their investment to pay off in reliability, and that expectation extends all the way down to the clamps. When EJP changed from BAND-IT to a cheap fastener made in China, the customer experience they delivered suffered – a direct result of the increased failure of the clamps.
Even though EJP had stopped using BAND-IT clamps, Fraser Ng, OEM/Project Manager for BAND-IT, maintained contact with them. “I had advised them of the high possibility that non-reputable companies in China may supply sub-standard quality . It really happened to them. The material they paid for did not meet their requirements.”
➡ BAND-FAST clamps can be secured with seals, clips, ear-lokt buckles or centre punch clips to meet all of your fastening needs.
