CMP secures major tunnel contract

CMP Products has secured a contract to supply cable restraining cleats for the multimillion dollar Singapore Tunnel Project.

SP Group’s Singapore PowerGrid (SPG) launched the project to future-proof Singapore’s electricity supply by installing a 40 km tunnel system to accommodate up to 1,200 km of high voltage cables in the power grid and distribution network.

Over the course of the project, more than 130,000 bespoke cable cleats – designed specifically for the project, with the capability to restrain substantial 230 kV and 400 kV cables – will be installed throughout several kilometres of the tunnel system.

The tunnel system is being installed at a depth of 60 m using a combination of horizontal excavation using rock blasting and tunnel boring.

The use of the tunnel system to install electricity transmission cables has been carefully considered; a history of traditional direct burial has caused the space beneath roads to become congested with gas pipes, water pipes, telecom cables, sewer lines, drainage channels and MRT tunnels.

If the direct method were used now, it would require significant diversion of services and create major disruptions to traffic and road use, thus installation through a trenchlessly installed tunnel provides the most cost-effective and least disruptive solution.

“Work on the Singapore Tunnel project demonstrates how rapidly CMP is capable of deploying our engineers, sales teams and product specialists to tackle very new, technical challenges to come up with a robust, practical solution,” said CMP CEO Vincent Patterson.

“This is a major success for CMP as we continue to demonstrate our capabilities in the cable cleat market; and later this year we will move our cleat production line into a new facility that will see us develop this area of our business even further.”
