CONTROL CABLES: BS :6346:1989  




CONTROL CABLES - As per Indian standard  IS:1554 (part -1)-1988 

CONSTRUCTION

Conductor
Copper conductors are made from high conductivity Copper rods of 8 mm diameter. The rod is drawn to required sizes for the construction of conductors of different areas of cross section conforming to IS:8130-1984. Conductors for Power cables with cross sectional area have following configuration
Conductors are either solid circular or stranded circular (non-compact) conforming to Table 1Class 1 or Table 2 Class 2 of IS:8130-1984.

Insulation
PVC Compound is insulated over conductor by extrusion process with required thickness of insulation and conforms to IS: 1554 (Part-1)-1988 specification for PVC insulated heavy duty cables.

PVC insulation, is either of general purpose 'type A' PVC compound, suitable for a maximum continuous conductor operating temperature of 70°C, or of Heat resistant 'type C' PVC Compound, suitable for a maximum continuous conductor operating temperature of 85°C conforming to requirements of IS:5831-1984. Special types of PVC insulation suitable for 105°C and FR / FRLS sheath can also be offered against customer requirement.

Identification of core colours:

No. of cores   Identification
2   Red and Black
3   Red, Yellow and Blue
4   Red, Yellow, Blue and Black
5   Red, Yellow, Blue, Black and Grey
6 and above   2 adjacent cores in each layer Blue and Yellow, remaining cores Grey

 








 



Laying up
Cores are laid up with right hand lay in the outermost layer in the sequence of above core colours. Interstices, if necessary, are covered with non hygroscopic fillers and covered with a binder tape for compactness and to maintain reasonably round shape.

Multi-core cables having more than 7 cores have the opposite direction of lay to that of the final layer of cores.

Inner sheath
All multi-core cables have either extruded PVC inner sheath or thermoplastic wrapped inner sheath, which is compatible to insulation material and removable without any damage to insulation.

Armouring
Multi-core armoured cables have either single layer of Galvanized Steel wire Armour or Galvanised steel formed wire (earlier steel strip) applied over inner sheath with left hand lay. Galvanised steel wires and / or formed wires (earlier called strip) conform to IS:3975-1998.

Outer sheath
For Cables with general purpose PVC insulation, Sheaths are extruded with Black PVC compound of type ST1 and for cables with heat resistant PVC insulation, sheaths are extruded with Black PVC compound of Type ST2 conforming to the requirements of IS:5831-1984.

PVC outer sheath with improved fire performance as per Category C1 and C2 are available against specific requirement. Outer sheath is embossed / marked with informations required by the relevant standard / customer requirement.

Packing, storage and handling
Cables for power supplies and control panel wirings are always packed in appropriate sizes of strong and seasoned wooden drums designed to withstand long distance transit and preservation in stores. Control cables of all sizes are packed in standard lengths of 500 metre 5%

It is advised that drums are always to be stored in concrete floors to avoid sinking in mud and damages or deterioration of drum flanges and shall not be stored on its flanges horizontal to ground. Drums are designed for easy handling when transported by cranes or mounted on cable drum wheels for laying. Cables in drums shall be stored away from boilers and furnaces.

Customer orientation
Against specific requirement and application, Q-Flx wires & Cables . can offer cables conforming to either customer specification or other National and International Standards.

Laying up

Cores are laid up with right hand lay in the outermost layer in the sequence of above core colours or numbers. Interstices, if necessarily agreed, are covered with non hygroscopic fillers and covered with a binder tape for compactness and to maintain reasonably round shape
.
Bedding

Control / Auxillary cables have extruded bedding. Which is compatible to insulation material and removable without any damage to insulation.

Armouring

Control / Auxillary cables of armourd type have single layer of Galvanized Steel wire Armour over bedding with left hand lay. Other armours like steel strip, tape can also be provided against customer specification.

Oversheath

Sheaths are extruded with Black PVC compound of type TM 1 and comply with the requirements of BS 6746:1990. When specified anti termite properties can be provided on the sheath. Overseath with Special flame retardant charactorstics can be supplied on request.

Packing, storage and handling

Cables for control panel wirings are always packed in appropriate sizes of strong and seasoned wooden drums designed to withstand long distance transit and preservation in stores.

Control / Auxiliary cables are packed in standard lengths of 500 metre ± 5%. It is advised that drums are always to be stored in concrete floors to avoid sinking in mud and damages or deterioration of drum flanges and shall not be stored on its flanges horizontal to ground. Drums are designed for easy handling when transported by cranes or mounted on cable drum wheels for laying. Cables in drums shall be stored away from boilers and furnaces.


Customer orientation

Against specific requirement and application, Q-Flx Wires & Cables . can offer cables conforming to either customer specification or other International Standards.

Current ratings

Current ratings of cables installed in air and around buildings reference should be made to’ Regulations for electrical installations' (IEE Wiring Regulations), 15th Edition and the current ratings of cables installed in other situations reference should be made to 'Current rating standards for distribution cables', ERA 69-30:Part Ill.
