HV Cable Cleats

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.

What standards does the range comply with?

All 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.

What materials are used for CMP’s High Voltage Cable Cleats?

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.

Bespoke HV cable cleats for specific project requirements

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.
