These are low voltage (0.6/1.0 kV & 1.8/3.0 kV), medium voltage (6.0 kV to 20 kV) & instrumentation cables (150/250V) in fire retardant and fire resistant combinations confirming to the construction and performance as per IEC 60092-353, 354, 376, 350, 352, 360. These cables are suitable to use in fixed installation in power, lighting, control, instrumentation and communication circuits on sea/marine vessels and offshore platforms where peak / transient voltages occurs during motor operations / variable frequency drive applications
These are single / multi core/pair cables with maximum conductor operating temperature of 90˚C and maximum conductor short circuit temperature 250˚C, produce low level of smoke and corrosive gases when exposed to fire than compared cables manufactured in accordance with IEC 60092-353, 354, 376.
Technical Specification
- Conductor: High conductivity annealed plain stranded copper conductor produced in-house from state-of-the art Contirod line.
- Insulation: In-house developed high insulation resistance cross-linked polyethylene thermoset insulation or Ethylene propylene rubber.
- Individual Shield: Where required Pairs are shielded with Aluminium. Mylar Tape along with drain wire Laying
- Inner Covering/ Inner Sheath/ Protective Tape: A protective barrier created between insulation and armour/braid/screen by extruded layer of polymeric material or Protective tape.
- Collective Shield: Where required laidup Pairs are shielded with Aluminium. Mylar Tape along with drain wire
- Metallic Braid / Screen: Copper Braiding / Screening is provided to allow the cable to withstand mechanical stresses to which it is exposed.
- Sheath: In-house developed thermosetting polyolefin compound type SHF-1 / SHF-2 having free from halogen, low emission of smoke and corrosive gases when exposed to fire.
