Equipment or hook-up wires are small insulated wires which are used extensively in all types of electrical apparatus. Originally developed for use in aircraft, PTFE equipment wires, due to their performance and reliability are now widely used throughout the industry, where environmental condition preclude the use of ordinary PVC insulated wires. The small size of PTFE insulated equipment wire coupled with high voltage rating saves valuable weight and space in miniaturization and the high temperature limits of PTFE enables soldered connections to be made without damaging adjacent wires.   We manufacturer PTFE insulated silver plated copper wire as per American Military Specification W-16878. Our PTFE wires are as per JSS specifications 51034. These PTE insulated hook-up wires are manufactured in different sizes and different voltages. We manufacture these wires according to American Wire gauge system. Normal size of wires varies from AWG 32 to AWG 12 in single strand as well as multistrand. Insulation thickness of these wire depend upon voltage ratings. Generally three different voltage codes for each type of voltage ratings. We can also supply the material for higher voltage for specific requirements. Chart sowing diameter of base conductor and diameter and diameter of insulated wires having different voltage rating are given SPECIFICATION PTFE INSULATED SPECIAL EQUIPMENT WIRES Please refer to table for commonly available sizes. Within the normal range, larger number of strands are available to improve flexibility and flex-life; 19 strands up to AWG 30, 37 strands up to AWG 20 and 60 strands for AWG 9, 10, 11, 12 and 13. In the two larger sizes AWG 6 and 8, compact 61 strands true concentric constructions (compared to Rope lay 19 x 7) are about 15% lower in OD, weight and cost, although slightly stiffer. We offer finer sizes, having thin-wall PTFE insulation, highly flexible (with flex-life) constructions using Silver Plated High Strength Copper Alloy (SPHSCA). Sizes as small as AWG 37/7/45 (0.43 mm). Even such fine sizes are 100% tested. For Wire-Wrap wire, advantages of PTFE insulation are now available in single strand size up to AWG 36 (OD 0.43 mm), and multi-strand 3607 or 3707 with OD 0.38 mm. SPECIAL FEATURES — QUALITY ASSURANCE 100% Physical and Electrical testing (see below for test voltages ) A minimum of 3 layers of PTFE tape, wrapped and sintered, provides balanced bi-axially oriented, concentrically placed insulation (for more details about advantages of TWS method, click here) Minimum shrinkage/deformation and no `run-away’ problem at soldering-iron temperatures Surface as good as extruded wire without the disadvantages of extruded PTFE insulation in fine-gauge thin-wall types Certified minimum BREAK DOWN VOLTAGE (on samples) to ensure higher, uniform and predictable performance Controlled tigher tolerance on weight, PTFE density and conductor resistance Test voltages for the three common working voltages are: Type Working Voltage AC RMS Dielectric Test Voltage for 1 minute Spark Test Voltage for for 1 second ET 250 1500 2500 E 600 2000 3400 EE 1000 3000 5000   CAUTION Thin-wall insulation is not recommended for higher soldering iron temperatures and for gauges larger than AWG 20 Stripping of Tape-Wrapped-Sintered (TWS) PTFE insulation is generally difficult on automatic high-speed machines, more so, for thin-wall finer sizes ADVANTAGES OF PTFE INSULATION PHYSICAL/CHEMICAL Inert to practically all chemicals even at elevated temperatures Excellent Resistance to Ultra-Violet radiation and stress-cracking Non-contaminating, Non-toxic and bio-compatible Resistant to fungus and mould growth HIGH TEMPERATURE Excellent thermal stability — suitable for use from -200°C to 260°C Fire (flame) proof Soldering iron resistant and suitable for high density wiring ELECTRICAL Suitable for very wide frequency range (DC to above 10,000 MHz) over wide temperature range Lowest dielectric constant (2.1) Lowest dissipation factor (below 0.0003) Highest volume and surface resistivities (in Teraohms) Corona Resistance is fair (CR PTFE is available for severe corona conditions) MECHANICAL Smaller size, lighter weight and much higher reliability Cold-flow and cut-through resistance — fair (good mechanical strength) Excellent flex-life APPLICATIONS OF PTFE INSULATED WIRES & CABLES Electronic Test Equipment Communication Equipment (mobile and manpack wireless sets) Equipment for Aircraft, Radar, Navigation, Electro-mechanical applications, Satellites, Research Equipment for Aerospace, Navy & Meteorology Control Equipment for Atomic Energy, Satellite Launching, Ground Control, Reactors and Process Control, Telephone Exchange, Lifts Computers, Flight simulators High performance motors, transformers and rectifiers Infra-red sensing equipment Thermo-couple and compensating cables Air-field lighting equipment High temperature lighting fittings (sodium lamps etc.) Refrigeration equipment Load cells and pressure transducers Electro-medical/Neuro-surgical equipment High temperature control valves Furnace and oven wiring PTFE INSULATED SPECIAL EQUIPMENT WIRES Please refer to table for commonly available sizes.
