To complement the existing range of electrical wires, Finolex introduces ‘Housegard’ - PVC-insulated electrical wires that offer added safety.

Each wire is manufactured using 99.97% pure, electrolytic grade, bright annealed bare copper with more than 100% conductivity. This copper is manufactured at the group company’s state-of-the-art plant in Goa. Better purity and conductivity of copper ensure greater electrical energy savings and thus help reduce electricity bills. The conductor is made of multiple strands of finely drawn copper wires, thereby offering greater flexibility, which makes these wires ideal for conduit wiring.

The wires are insulated with PVC compound, specially formulated and manufactured in-house. A special grade PVC resin manufactured by the group company, Finolex Industries Limited, is used to manufacture this compound. This PVC compound has a high oxygen and temperature index. These properties help restrict the spread of fire even at very high temperatures. This unique compound also offers high insulation resistance and dielectric strength. Insulation is applied over the conductor by the process of dual extrusion using state-of-the-art extrusion lines. The outer skin determines the colour identification, while the inner layer is pure insulation, which provides extra protection.

All wires are subjected to high-voltage spark testing to ensure that there are no weak spots in the insulation. These ISI-marked wires meet the requirements of IS 694: 1990, which means extra protection against electrical shocks, short circuits, and fires. The wires also have FIA/TAC (Fire Insurance/Tariff Advisory Committee) approval.

The company name, size of wire, voltage grade and logo are printed at regular intervals on the wire to help in easy identification as shown below.

About

For the first time in India, Finolex is offering ‘Flamegard’—Flame-Retardant Low-Smoke (FRLS) electrical wires. Flamegard is manufactured using electrolytic-grade copper to ensure superior conductivity. Insulated with an FRLS PVC compound formulated and manufactured in-house, Flamegard has special flame-retardant, low-smoke-emitting, and toxic fumes-suppressive properties in addition to those required by IS 694: 1990.

During a fire, ordinary PVC insulated wires give out thick black smoke and toxic fumes of hydrochloric acid gas. This impairs visibility and hampers rescue operations. FRLSH, on the contrary, not only emits very little smoke and toxic gases but also retards the spread of fire. It goes through rigorous tests to ensure the highest standards of quality. It is also backed by the Tariff Advisory Committee and Fire Insurance Approval.

These wires are provided with an orange stripe for unique identification upon request.

About

Finolex makes three-core flat cables best suited for submersible applications. They are manufactured with a conductor using annealed bare copper wires of electrolytic grade and bunched properly to ensure desired flexibility. The conductor is further insulated with thermoset type Cross-Linked Polyethylene (XLPE) of uniform thickness, with each of the core colours in red, yellow and blue, using most modern machinery and extrusion techniques.

The sheath with a uniform thickness of Heat and Moisture-resistant type PVC (Grade ST2) compound formulated and manufactured in-house is extruded over these coloured cores in a flat formation. The colour of the sheath is black. The cables undergo stringent quality checks during raw materials, in-process and final testing as per the specifications and quality norms that are laid down. The cables are available with progressive sequential marking, company name, size & voltage printed on the sheath.

The following are the advantages offered by XLPE insulated cable over PVC insulated cables:

• Higher current rating: It can withstand a continuous conductor temperature of 90 °C against 70 °C for PVC. This means a higher current carrying capacity, so it is possible to use one size lower than PVC for the same current. These cables can withstand extreme voltage fluctuations.
• Higher overload capacity: It can withstand up to 130 °C during emergency overloading, as against 120 °C for PVC. Hence, in case of emergency, it can be sustained for a more extended period of time than PVC.
• Higher short circuit rating: It can withstand up to 250 °C under short circuit conditions, as opposed to 160 °C for PVC.
• Lighter in weight and smaller bending radius: Its lower density than PVC makes it lighter in weight, and hence, its bending radius is smaller than that of PVC.
• Lower dielectric constant and power factor: This saves on power losses, which means savings on costs.
• Better impact, abrasion, and corrosion resistance: It is safer than PVC cables against mechanical damage, abrasion and corrosion.
• Easier jointing and termination: No special skills or equipment are required for jointing and termination.

Applications:

• Submersible pump motors
• Water Supply
• Sanitation

About

Finolex co-axial cables offer higher bandwidth, so your customers can receive the maximum number of channels with high picture and sound quality. These cables are uniquely designed for specialised applications. This translates to more happy customers, more extensive cable TV networks and more profits for the cable operators. The cable is with a central conductor of copper-clad steel (CCS), which offers high mechanical strength and hence can support a more extended span without stretching. The cable withstands all mechanical abuses during operations. Due to the principle of skin effect, the copper cladding over the steel conductor carries a signal without any loss of signal quality.

Applications:

General Engineering

• Consumer Electronics
• DTH and CATV networks

About

Finolex’s 25-pair Cat-5 LAN cable for indoor application consists of a solid bare annealed copper conductor of 24 AWG (0.5 mm), insulated with High-Density Polyethylene compound, colour-coded, paired as per colour combinations given in the table. Twenty-five such pairs are twisted together to form a laid-up cable, and a nylon binder is applied helically. The cable is jacketed with a special FR PVC compound formulated and manufactured in-house with a high Oxygen and Temperature Index. The colour of the jacket is grey. The cable is ideal for use in vertical backbone structured cabling.

In the case of aerial cable, polyester tape is applied around the 25 pairs, along with poly laminated aluminium tape applied with an overlap. It is then jacketed along with a stranded galvanized steel wire strength member with a black-coloured polyethylene compound. The cable construction forms ‘Figure 8’ when seen in a cross-section. The cable is most suited for outdoor installations.

Applications:

• Voice & Data Transmission
• Broadband application

About

Finolex twisted paired cables are best suited for telephone cabling applications. The conductor is made of solid annealed, electrolytic grade high conductivity bare copper. The conductor is insulated with special-grade high-density polyethylene with different colours. The insulated cores are twisted with uniform lay to form pairs and are bunched together in such a manner as to minimise cross-talk. In 50 and 100-pair cables, the units of 10 and 20 pairs, respectively, are identified with colour binders and stranded to form the laid-up cable. The laid-up cable is further jacketed with a grey colour fire retardant (FR) PVC specially formulated and manufactured in-house, with a high oxygen and temperature index.
