Prysmian Cable Cleats

Cable Cleats – LV MV HV 11kV 33kV

Prysmian Cleats

Prysmian cable cleats are specified to provide cable protection in the event of a short circuit situation – this includes providing cable clamping and support to LV, MV & HV cables operating at 11kV-33kV.

Specialist cable cleats, saddles and supports are also available for EHV (Extra High Voltage) cables operating at transmission and distribution levels (132kV, 245kV, 400kV).

Cable Cleats – Advantages

  • Cleats ensure orderly LV-HV cable installation allowing cable to be used at optimum rating
  • Maintain cables in position allowing reworking in safe conditions
  • Cable cleats provide restraint against short circuit current forces, including 11kV and 33kV

Selecting & Specifying Cable Cleats

LV MV HV 11kV 33kV

Cable cleats are available in plastic (nylon and LSF), stainless steel and aluminium – the following information enables the selection of cleats in order to achieve compliance with IET 17th Edition Wiring Regulations.

11kV 33kV

MV HV Cable Cleats

522.8.4 “where the conductors or cables are not supported continuously due to the method of installation, they shall be supported by suitable means at appropriate intervals in such a manner that the conductors or cables do not suffer damage by their own weight” (1)

522.8.5 “every cable and conductor shall be supported in such a way that it is not exposed to undue mechanical strain and so that there is no appreciable mechanical strain on the terminations of the conductors, account being taken of the mechanical strain imposed by the supported weight of the cable or conductor” (1)

(1) 522.8.4, Extracts from BS7671 – IET 17th Edition Wiring Regulations 

Specialist application cleats include fire resistant cable cleats (suit Prysmian Draka FP, Afumex, FT and Saffire cables), epoxy coated cleats for harsh and hazardous area applications where salinity, chemicals, pollution, high humidity and high temperatures exist.

IEC 61914 The International Cable Cleat Standard

Prysmian cable cleats are tested to European and International standard BS EN 61914:2009 (IEC 61914) – short circuit currents generate potentially catastrophic forces. In view of sizing an LV-HV electrical installation and the associated cable cleats, accessories and electrical equipment, as well as determining effective protection of both life and property, short-circuit currents must be calculated for throughout the cable network circuit.

IEC 60909-0:2016 is applicable to the calculation of short-circuit currents in LV low voltage three-phase AC systems and in HV high voltage three-phase AC systems.
