Zinc wires are packaged in coils or spools of continuous length. The minimum mass of the coil is 25 kg unless there is a customized requirement. Spools have a minimum mass of 10 kg. The coils are individually wrapped in polythene sheet/ gunny sheet.

The Tin-Zinc alloy wires have good mechanical strength and solderability. They can provide the sprayed metal layer of film capacitors with strong adhesion ability, and give capacitors good electrical performance such as reduced loss angle. They are complaint with EU RoHS and WEEE directives on lead-free electronic products, as well as the requirements of ISO 14000 system.

They are most commonly used in DC & AC capacitor manufacturing units for spraying the ends of wound elements of capacitors.

Solder is a metal wire with a low melting point. For electronics, it is traditionally a mix of tin and lead. Other alloys are used for plumbing, mechanical assembly and other applications. The various types which are manufactured are Rosin Core Solder Wire, lead-free solders, solder alloys, silver solder, solder plates, silver sticks etc. to keep up with the continuously changing electrical and electronic field.

Their individual usage ranges from being in demand in the entertainment and professional electronic, defense electronics and avionics fields and industry. Also is used in the mass production of capacitors, fuses etc.

SMA's bare copper wire are made from pure electrolytic grade copper and are manufactured in compliance with required standards.

Solid wire has only one strand of bare copper metal wire which is surrounded or sleeved by and insulator. This Solid wire is used in enamelled wired motors and transformers. As these wires are rigid - they do not bend easily, and hence their application is where there is no frequent use to remove it. Once it is fixed it almost becomes permanent, and hence it is used in low flex applications.

Stranded wire is a bunch of thin copper wires braided and twisted together and sleeved by and insulator. Stranded Copper wire is very flexible and is easier to use or install than the single solid wire for the same purpose. Stranded wires are used where there are vibrations observed. The reason is that as it is twisted into the sleeve the conductivity and the resistance is better. Here the added advantage is it has the same characteristics and better flexibility.

Cable cords available from 2 wires to 12 wires

A thin copper cable is a cable where two or more separate copper wires are bonded together in a different sleeve but braided together. The use of these cables is especially for electronic equipment industries.

Copper wires in these cables would be bare copper or are plated to minimize oxidation with tin, silver or gold as per the use of the equipment or on the need of the customer.

Enamelled Wire is a Copper Wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, and other applications which require tight coils of wire.

A transformer is a device that transfers electrical energy from one circuit to another through its coils (windings). The properties needed for motor windings are similar to those needed for transformers, but with the additional requirement to withstand mechanical vibration and centrifugal forces at operating temperatures.

The wire itself is most often fully annealed, electrolytically refined copper. Copper Enamelled Wires are often used to improve energy efficiency in electric motors.

Thicker Enamelled Wire is often square or rectangular (with rounded corners) to provide more current flow per coil length.

The most suitable materials for Enamelled wire applications are unalloyed pure metals, particularly copper and aluminium. Copper is considered the best choice conductor for Enamelled wire in terms of chemical, physical & mechanical properties required.

Most often, Enamelled wire is composed of fully annealed, electrolytically refined copper to allow closer winding when making electromagnetic coils. The wire is coated with a range of polymeric insulations, including varnish, rather than the thicker plastic or other types of insulation commonly used on electrical wire. Polyimide insulated magnet wire is capable of operation at up to 250 C.

Self-supporting coils are wound with wire coated with at least two layers, the outermost being a thermoplastic that bonds the turns together when heated.

Other types of insulation such as fiberglass yarn with varnish, aramid paper, kraft paper, mica, and polyester film are also widely used across the world for various applications like transformers and reactors.

Enamelled Wire are classified by diameter (AWG number, SWG or millimeters) or area (square millimeters), temperature class, and insulation class.

Breakdown voltage depends on the thickness of the covering, which can be of 3 types: Grade 1, Grade 2 and Grade 3. Higher grades have thicker insulation and thus higher breakdown voltages.

The temperature class indicates the temperature of the wire at which it has a 20, 000-hour service life. At lower temperatures, the service life of the wire is longer (about a factor of 2 for every 10 C lower temperature). Common temperature classes are 105 C, 130 C, 155 C, 180 C and 220 C.

Enamelled Wire can work continuously for 155 C and
