HVSS-CC High voltage trefoil cable cleat with closed centres. (Fixed and sliding base variants available).

CMP HVSS-CC trefoil cable cleat is an extension to the range of HVSS products, for the safe retention of high voltage cables. The range has been designed, constructed and tested
(as HVSS-EC) 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). The product variations comprise of a fixed and slide cleat.

The HVSS-CC trefoil range of cable cleats are designed for use with high voltage cable installations and are manufactured to suit a range of cable diameters.

The range consists of three cable cleats designed to be installed as a system; a fixed cleat, a slide cleat and an intermediate restraint (if required).

The HVSS-CC fixed cleat is designed to secure the cables in a trefoil formation to a mounting surface, providing excellent axial and lateral retention. In between these fixed cleats, slide cleats are installed to allow for the expansion and contraction of the cables in their normal operating conditions. Slide cleats are designed with a fixed bracket rail on the underside of the cable cleat base; this enables the cleat to move along the rail ensuring a trefoil formation, cable integrity and allowing HV cables to move within their cable ‘snaked’ formation as a trefoil configuration, keeping the three phase system as balanced as possible. Intermediate restraints may be installed between the fixed and slide cleats to further improve the integrity of the system.

Both the slide and fixed variants can be installed as ‘stand alone’ products offering flexibility to the installer, alongside Intermediate restraints where required.

HVSS-CC cleats are fabricated in non-magnetic 316L stainless steel. Flame retardant low smoke and fume fixed liners are fitted as standard, helping to:

• Restrain the cables within vertical applications.
• Provide a layer of protection to both the cable sheath and the cable cleat, during normal operation where thermal elongation of cable occurs.
• Protect the cable from chafing on any mounting surface due to differential movements, such as those found in marine and offshore applications.
• Assist in the extra protection of cables in the event of short circuit fault conditions.
