As part of its comprehensive cable cleat range, CMP offers a selection of high voltage (HV) cable cleats that are designed to safely restrain high voltage cable (s). CMP is able to provide cable cleats for any level of cable voltage; for example 3.3kV, 230kV or 1,000kV.
Manufactured from the highest quality materials, CMP’s HV cable cleat range has excellent corrosion resistance, strength and durability, making them suitable for use in the harshest of environments.
Designed and manufactured in accordance with the International Standard IEC 61914: Cable cleats for electrical installations, CMP cable cleats undergo rigorous short circuit testing.
CMP designed two bespoke trefoil cable cleats for high voltage cable for the major, and highly technical Singapore Tunnel Project. Read more about our innovative solution for the project here.

Jump to productsAll CMP high voltage cable cleats are third-party certified in accordance with the International Standard IEC 61914: Cable cleats for electrical installations, to ensure the securing and retention of cables without sustaining damage to the cable(s).
Where specific client requirements mean that the short circuit test parameters fall outside of the criteria laid out in IEC 61914; for example the customer specific size of cable to be tested is larger, or the number of cleats per test setup is smaller; then the test procedure and criteria of IEC 61914, and the customer’s test requirements, are both adhered to.
CMP has conducted numerous additional client specific tests, with certification obtained as required on a project specific basis.
CMP’s high voltage cable cleats are manufactured from the highest quality 316L stainless steel to provide products with high creep strength and excellent corrosion resistance.
A selection of products within this range are also available in aluminium. The grades of aluminium we use are selected for their high corrosion resistance and superior tensile strength.
Cleats can be optionally powder coated – CMP offers standard Epoxy or Polyester powder coating. A polymer alloy coating which is UL94 V0 flame retardant, and Low Smoke and Fume Zero Halogen (LSF0H) is also available.
The polymer cleat liners supplied as standard are classified as Low Smoke and Fume Zero Halogen (LSF0H) and Phosphorus-Free.
CMP works with clients to design and manufacture bespoke cable cleat solutions to cater for specific project requirements. We can supply industrial products which do not require certification, designed to exact requirements.
We also offer a design service which includes all testing and third party certification of the products.
Using Finite Element Analysis (FEA) during the product design process, CMP’s dedicated cleat development team are able to model the stresses on cable cleats under short circuit situations, allowing them to make accurate predictions as to how products will perform when installed. This saves vast amounts of time in the early development and testing phases, reducing the overall lead time for our customers.
CMP developed two bespoke trefoil cable cleats for 230kV and 400kV cable for the major and highly technical Singapore Tunnel Project. Read more about our innovative solution for the project here.

Cable cleats are devices designed and tested to ensure the retention and support of cables, and have been used for many years all over the world.
It was not until 2003 with the emergence of the standard EN 50368, that any standard for cable cleats existed. This not only highlighted the retention and support that cable cleats provided to cables, but more importantly highlighted the protection of the cable management system and the potential risk to human life without the use of cable cleats. Prior to EN 50368 both cable and cable cleat manufacturers provided testing to their own standards.
This was then followed up with the publication of IEC 61914 in 2009 and superseded by a new standard in 2015 which further highlighted the importance of cable cleat products, and correct cable cleating.
IEC 61914 – Cable Cleat
‘Cable cleat’ according to IEC 61914 defined as: “A device designed to provide securing of cables when installed at intervals along the length of cables.”
“Note: A cable cleat is provided with a means of attachment to a mounting surface but does not rely on an unspecified mounting surface for the retention of the cables. Examples of mounting surfaces that may be specified are ladder, tray, strut, or rail, wire and beam. Where declared, cable cleats provide resistance to electromechanical forces.”

By ensuring the cables are fixed, retained and supported correctly, cable cleats protect all of the cable terminations by reducing the mechanical load exerted on them.
CMP cable cleats are designed and tested so that in the event of short circuit fault conditions, they will contain the cables without causing damage; enabling the circuit to be restored once the fault has been rectified.
The latest standard IEC61914 specifies requirements and tests for cable cleats and intermediate restraints, used for securing cable in electrical installations.
CMP cable cleats provide the necessary levels of resistance to electromechanical forces, where declared, and in addition achieve the following safety measures:
