  Selection of Power Cables     Power cables are generally selected considering the application. However followingfactors are important for selection of suitable cable construction required to transport electrical energy from one end to other.     Maximum operating voltage     Insulation level     Frequency     Load to be carried     Possible overloading duration & magnitude     Route length and voltage drop     Mode of installation considering installation environment such as ambient & ground temperature.     Flame retardant properties     Plant safety requirements

Applications       For transmission of analogue and digital signals in instruments and control systems without any external interference.           Classification     Paired element Signal cables  ( 4 to 20 mili amps )     Triad element Signal cables ( RTD application )     Quad element Signal cables     Pentad element Signal cables     4 pair unit elements Signal cables     Multi-pair Analog / Digital Signal cables upto 128 pairs           Standards     BS 5308 Part 1     BS 5308 Part 2     ENI     IEC 189     NEMA WC 55     IEC 227     Customer Specification           Typical Constructions for Instrument Signal Shielded Cables     Conductor :  Electrolytic grade annealed bare / tinned copper, either Solid/Stranded/Multistranded conductors.     Range : 0.5/0.75/1.0/1.5/2.5 Sq.mm     Voltage grade :  (300v/500v – 4 to 20 mili amps)     Insulation  :  General Purpose PVC/ Heat Resistant PVC/ LDPE/XLPE/ZHLS     Identification :  Color code / No. Printed tapes over pairs/ Ring marked/ Dual color extruded.     Screening  :  Individual and / or overall with Aluminium-Polyster tape with tinned copper drain wire / Bare/Tinned Copper                          Wire Braid / Copper Tape with drain wire.     Inner Sheath :  PVC/ HRPVC/ FRPVC/ FRLS PVC/ ZHLS     Armour :  Hot Dip Galvanized Steel Round Wire / Strip.     Outer Sheath :  PVC/ HRPVC/ FRPVC/ FRLS PVC/ ZHLS

  Fire Survival cable properties  :     Low Halogen Emission :  Virtually free from halogen gases.           Flame Retardant :  Reduced flame spread and self-extinguishing once the flame is removed.           Non-flame Propagation :   When ignited by a flame source does not allow fire to spread even if a cable bundle is placed vertically. Cable are self - extinguishing once the flame is removed.           Low Toxic Gas Emission :  During fire condition small quantity of toxic gases mainly, CO, CO2 are inevitably emitted. Fire Survival Cables are designed to limit these toxic gases within safety level.           Low Emission of Corrosive Gases :  Corrosive Gases react with moisture to produce active acids which corrode metals causing extensive long term damage. Often these gases spread throughout the building through the ventilation system or within the entire installation. This is particularly damaging to electronic equipments and even to the exposed steel structures or even the concrete enclosed steel structures.           Reduced Smoke Emission :  In fire condition smoke emission greatly hampers visibility to an extent that escape and rescue routes are not recognisable. This jeopardises the safety of people in public buildings, station, airports, hotels, subways station etc.           High Inflammability :   It is preferred at high temperature the mechanical strength should be retained to a minimum level and are infusible (i.e. the insulating and sheathing material does not drip) and therefore ensure high short circuit security.      

n keeping with the company's commitment to technological advancement, elastomer materials such as Polychloroprene (PCP), Chloro-Sulphoneted Polyethelene (CSP), Nitrile Rubber / PVC blends, Ethylene Propelene Rubber (EPR), Ethylene Vinyle Acetate (EVA) and Silicone have been specially compounded to meet numerous heat oil and fire resisting requirements. In the recent years Udey Pyrocables has also developed special Elastomeric Fire Survival Cables for power, control and instrumentation wiring. Applications : Reeling unreeling, Trailing, Festooning, Cranes, Conveyors, Mobile MachinesElastomeric compounds for insulating and sheathing of cables are formulated to meet the requirement of IS 6380, BS 6899, IEC 60502 and other international specification.
