Conductor

All of our copper conductors are made from high conductivity copper rods. These 8 mm diameter rods are made from 99.97% pure, electrolytic grade, bright annealed bare copper with an excess of 100% conductivity. This grade of copper guarantees a low energy loss due to line irregularities and inefficiencies which can result in lower electric usage. The rod is drawn to the required wire size for the wire that is being manufactured. Annealed plain copper conductors used in flexible cables and cords conform to the requirements of table 3 Class 5 of IS:8130 -1984. Custom sizes can also be made for specific customer needs, as well as custom colors for job specific requirements.

Insulation

Ratansiri House wires are mainly available readily in PVC insulations & also manufactured in various other insulations like, FR PVC / FRLS PVC / HR PVC / Zero Halogen & PTFE With HR PVC.

 — PVC Insulation

The insulation of the wire is achieved by using a Type ‘A’ PVC compound suitable for a maximum continuous conductor operating temperature of 70º to conform to IS:694-1990. The wire is insulated by means of an extrusion process which generates the required insulation thickness for the job, and they all conform to the requirements set forth in IS:5831-1984.

PVC forms the basis of all of the following forms of insulation, but different formulations have been designed to fit certain legal and customer requirements. If you have any questions about specific applications of any of these insulators or any of our other products please be sure to contact out customer service experts.

 — FR Insulation

FR PVC insulation has better fire retardant properties than normal PVC. This FR PVC compound has a high oxygen and temperature index. The wires are wadded with a flame retardant (FR) PVC compound, which helps to control the spread of fire even at very high temperature. It also protects against electrical shock and short circuit.

 — FRLS Insulation

Whenever a fire breaks-out in any building/Complex, the burning of wire emanates, the toxic, black smoke, which causes injury and subsequently becomes fatal to the human life. FRLS PVC insulation provides better fire retardant properties than normal PVC & also emits Low Smoke, in case of fire.

 — HR PVC Insulation

Depending on where you live and how a structure is built, some wires may routinely be exposed to temperatures which would degrade wires made from the normal formulations of PVC. To counteract this, Ratansiri has formulated our Heat Resistant PVC insulation to specifically address situations where a heated resistant wire is needed. The HR PVC Insulation ensures stability at conductor temperatures of 85ºC and 105ºC and are designed to adhere to the standards set forth in HR85 and HR 105 PVC.

 — ZERO HALOGEN Insulation

For extreme uses, Ratansiri’ Zero Halogen insulation holds the highest heat resistance, making it the best flame retardant insulation. This is critical for certain uses, including buildings which would routinely house large numbers of people or critical infrastructure. Zero Halogen insulation requires temperatures in excess of 300ºC to catch fire with a 1% Oxygen atmosphere.

Zero Halogen is critical when you must maintain control of electrical components for as long as possible if a fire should break out. Because of the high ignition properties of this insulation, the onset of smoke and an extra flame source will help control the spread and devastation of the fire, at least to a small amount.

 — PTFE With HR PVC Insulation

PTFE with HR105 PVC is designed for high cost and sensitive installations where fire from electrical short circuits may cause damage to human life & property. PTFE can withstand, operating temperature from -650C to +2600C.
