Which Access Chamber Can Be Built Faster?

Access Chamber Testing

The following Access Chamber test, performed by Cubis, has taken place in order to determine which Chamber Access method performs the best and can be installed the fastest – the time trial provides a comparison between conventional brick built and modern technology modular style access chambers.

access Chamber Testing

Access Chamber Trial

After testing, it can be concluded that the STAKKAbox™ Modula access chamber is significantly faster to install when compared to a traditional Brick Footway access chamber. This is also factoring in the depth of the the Modula access chamber, which is almost double that of the brick. The STAKKAbox™ Modula access chamber has been found to be suitable for vehicular trafficking in pedestrian areas, which is achieved immediately.

issues with the brick access chamber

• There are potential RSI & H&S issues found in the construction of traditional brick installation, including:
  • Repeatedly bending over
  • Hard manual labour (over 24hours 45 mins period)
• Extra resources & building materials required to construct a traditional brick installation

STAKKAbox™ Modula Access Chamber:

• saves time
• saves money
• improved health and safety
• easy and fast access
• protection
• adheres to worldwide CRH standards
• easy assembly and installation
• flat pack option, making shipping more efficient
• variable sizes
• constructed from recycled material

STAKKAbox™ Chambers are significantly faster to install than conventional alternatives, with complete installations typically taking under one hour. This results in reduced costs for the installer and significant time saving. No specialist equipment or plant is required in order to install an access chamber and there is no need for specialist box builders. With flexible installation, Cubis access chambers can be adapted to suit on-site conditions with standard tools to build over existing networks.

Stokbord Drum | Cable Protection for Underground Utility Cables

Stokbord Drum Cable Protection for Underground Utility Cables

Stokbord Drum

MV HV Cable Protection for Underground Utility Cables

Centriforce, working through their distributor network including Thorne & Derrick, announce a new cable protection product that can help to improve working safety for utilities applications – known as the Stokbord Drum.

Stokbord Drum cable protection is supplied on a reel allowing minimal effort for the cable cover to be rolled out across expansive areas; a change from the tedious task of laying individual 1m cover sections.

Stokbord Cover is the “go-to” solution with a proven track record for offering heavy duty protection for buried cables and utilities – suitable for major infrastructure projects were speed of installation of operative’s safety is the top prioritises. The drum system also helps to increase safety as it gives a clear visual warning of the presence of underground pipes and medium/high voltage cables.

Stokbord Drum

The new Stokbord Drum system has been developed to provide a mechanical installation option decreasing the need for any manual work.  It reduces the manual labour involved and provides a safer environment as workers spends less time in the cable trench. As well as supporting safety on site, the Stokbord Drum also delivers a sustainable solution as it is manufactured from recycled polyethylene waste.

With all the benefits of the traditional Stokbord Covers, and a simple, less manual installation process, the Drum delivers improved safety and value for large scale operations.

Stokbord Drum Features

• Time saving installation for cable protection at LV MV HV EHV
• Lower risk to operatives and cable installation teams
• High impact resistance – cable protection does not shatter on impact
• Provides clear visual warning with bright colours and bold warning text
• Rot resistant and chemically inert meaning a long service life
• Cable covers conform to internationally recognised standards (e.g. BS 2484)
• Tried and tested by UK Distribution Network Operators and their contractors

Stokbord Drum offers a faster and safer way of installing Stokbord Cover utility protection. Stokbord Cover is approved and specified by utility companies throughout the world. It offers high visibility and prevents damage to buried HV cables and other utilities including gas, water and telecoms.

Stokbord Sheet is manufactured from post-consumer and post-industrial recycled plastic. This means that there can be some variability in product performance and within finish and colour uniformity. The degree of variability is controlled by our ISO 9001 Quality Assurance scheme.

Please Note: All plastics are susceptible to thermal expansion and contraction with temperature changes.

Manufactured from high impact resistant recyclde polyethylene, Stokbord Cover is able to withstand damage from both hand tools and mechanical plant.

Stokbord Drum was launched at Utility Week Live where Centriforce demonstrated the ease of installation of the new drum system to our clients, alongside our full utility protection range with Tapetile and Locata products.

Stokbord® Drum has since been successfully used on a number of large projects across the UK.

Centriforce Tapetile and Stokbord underground cable protection tiles and covers are the market leading, heavy duty utility protection system for protecting underground cable and pipes – this includes low voltage, medium voltage and high voltage power networks working at 11kV and 33kV.

Cable Winch | Customised & Refurbished 5 Tonne Cable Pulling Winch

Cable Winch

• uploaded by Chris Dodds - Sales & Marketing Manager with Thorne & Derrick International

Thorne & Derrick, the Specialist Distributor of LV HV Jointing, Earthing, Substation & Electrical Eqpt have supplied a cable winch requirement to a leading provider of offshore power distribution to the renewable and oil/gas sectors. 

The 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.

Additional features Pre-Set Load Function, Load Display, Test Certification & Load Cell.

Option 2 – Limited Lay Down / Wet Storage

Galvanised grips with galvanised steel ferrules for installation / loading with limited wet storage that can be further extended for longer wet storage with the addition of an anode.

Option 3 – Lay Down / Wet Storage up to 1000 Hours

Stainless steel cable grips with stainless steel ferrules for laying and limited wet storage up to <1000 hours, subject to inspection after such time elapsed.

Option 4 –  Lay Down / Wet Storage over 1000 Hours

Non-metallic grips in Aramid for used for cable laying and wet storage applications over >1000 hours, these would be the preference of the leading installation contractors based in the Netherlands and Europe, degradation was not seen other than some signs of salt on the surface. Non-metallic cable grips are specified to provide safe cable handling and are used for offshore saltwater environments when prolonged lay down durations are required.

LACE-UP CABLE socks

Mainly used where a ‘typical’ cable sock cannot be fitted over a connector at the end of a cable, ‘L-type’ cable socks are used in cable pulling when the end is not accessible. The mesh is wrapped around the cable, then closed with the wire lace provided.
