Wires that prevent the spread of fire.
Wires that protect you.

Electrical fires are the most common fires today, but it is the spread of the fire that adds to the danger. Norfix's Flame Retardant (FR) grade wires will add a layer of protection to your life. These wires have a temperature index of greater than 250 ºC ensuring that in the case of high temperatures the wires do not melt. In addition, the high oxygen index of 31% present in these wires ensures that in case these wires do catch fire they are self-extinguishable and thus prevent the spread of fire.

Applications

Wiring in all installations where fire safety is more important. Schools, theaters, commercial complexes, air conditioned apartments, high rise buildings, fire alarms and emergency lighting circuits.

Specifications

Generally conforms to, IEC 60332-1 & 3, IEEE 383, IEC 60754-1 & 2, IS-8130, IS-694, IS-5831.

Conductor

Thin strands of Electrolytic Copper are multi–drawn simultaneously for uniformity of Resistance, Dimension, and Flexibility. The drawn strands are bunched in high precision machines. A circular conductor is thus formed. The conductor is bunched in such a way that it reduces in overall diameter for space saving in high density wiring.

Insulation

Specially formulated grade of Flame Retardant (FR) compound is used. The performance of the cable in a fire situation is exceptionally good. The insulation does not burn readily. It does not melt and drip. The smoke is negligible, transparent, non toxic. The victims trapped in fire do not suffocate and this facilitates fire fighting operations. Unlike general purpose PVC, the smoke emitted is non-corrosive. Thus, the electronic printed circuit boards, hard disks and other sensitive electronic equipments are unaffected.

Marking

The cables are marked “NORFIX CABLES-FR (Size)1100V IS:694 CM/L NO-3067047”.

Colours

Red, Yellow, Blue, Black, Green.

Rugged cables for flawless and constant power transmission

Performs in the toughest Conditions

The Submersible cables are usually installed in conditions that are considered less than optimum. That’s why the three copper conductors inside are insulated with a special PVC compound. The outer sheath is made from a special grade of abrasion resistant PVC compound that is resistant to water, oil, petrol, most acids, alkalis and grease. With Norfix submersible cables, you are assured of optimum performance irrespective of the conditions.

Powering the world

This connecting cable is used for trouble-free working of submersible pump motors. Norwfix 3 Core Flat Cables are manufactured keeping in mind the severe and difficult conditions in which they are required to perform. The individual conductors are made of bright electrolytic grade copper. These wires are drawn, annealed and bunched properly to ensure flexibility and uniform resistance. Each of the 3 copper conductors is insulated with special PVC Compound. The cores are laid up in flat parallel position. The outer sheath of the cable is made from a special grade of abrasion resistance PVC Compound impervious to water, grease, oil etc.

Submersible 3 Core Flat

Norfix flat cables provide energy to submersible pump motors. The individual conductors are made of bright electrolytic grade copper. The cores are insulated with a high dielectric grade PVC compound. The outer sheath is made of a special grade of abrasion-resistant PVC compound impervious to water, grease, oil, etc.

Invariable power at all times

While single core cables are widely used for domestic purposes, multicore cables are used in areas where space might be a constraint (medical equipment, aircraft) or in entertainment venues, theaters, heavy industries, etc. The single as well as multi core cables from Norwood are durable and heat resistant. They do not melt or burn easily even in extreme conditions.

Features

Manufactured from bright annealed 99.97% pure bare copper conductors these cables offer low conductor resistance. These wires are insulated with in house manufactured specially formulated PVC compound. The tough robust outer PVC jacket protects it from oils, greases, various chemicals and abrasions giving the wire a long life and ensuring electrical safety

Applications

Multicore Cables are very versatile and can be used in control panels for heavy industries, heavy machineries, air-condition, motors etc.
