Caledonian FIREGUARD Cables

CABLE CONSTRUCTION
FIREGUARD cables are constructed in the following typical design:
  1. Solid/stranded annealed copper conductor
   2. Glass mica tape/silicone rubber as flame barrier
  3. XLPE/PVC as insulation
  4. Normal or Flame retardant FRPVC as sheath
FIREGUARD cables are offered in either single core, multicore or multi-pair constructions.
The insulation material is usually PVC with different levels of fire retardance properties to meet different stringent environment requirement. The cables may be armoured or braided, with or without metallic screen, depending on different applications.

INTERNATIONAL STANDARD
The FIREGUARD cables manufactured by Caledonian comply with either one or combination of the following standards.
IEC 60332-1
IEC 60332-3C

PRODUCTS

Fire Retardant PVC Sheathed Cables (FIREGUARD)
Flame Retardant Power & Control Cables
XLPE Insulated, PVC Sheathed, Screened Power Cables (3C+3E)
APPLICATION
The cables are designed specifically to suit the broad spectrum of requirements of Variable Speed
Drives and also include features for reducing the transmission of electromagnetic interference.
These range of cables are able to reduce capacitance of power conductors and have an electrically
balanced construction which includes split earths and a copper screen.
This range of screened cables drastically reduce interferences from electrical noise, especially in Variable Speed Drive (VSD) applications and are manufactured with fixed conductors.
With shield conductivity of 1/10th of phase conductor conductivity, this range of VSD cables
effectively restrain radiated and conducted radio-frequency emissions.
STANDARDS
Basic design adapted to IEC 60502-1
VOLTAGE RATING
600/1000V
CABLE CONSTRUCTION
Conductor: Plain annealed copper wire, stranded according to IEC(EN) 60228 class 2.
Insulation: Extruded cross-linked XLPE compound.

anti rodent and anti termite properties can be offered as option. Compliance to fire performance
standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the
PVC compound and the overall cable design. LSPVC can also be provided upon request.
