PTFE/FEP/ETFE INSULATED ROUND AND FLAT MULTI-CORE CABLES

GARG PTFE/FEP/ETFE insulated multi-core cables are required mainly for high-reliability and high-temperature interconnections for signal and control applications.

GARG offers any number of pairs, triads, quads, coaxial cables etc. combined into one large cable, with or without shielding on individual pairs/triads/quads, as well as with overall shielding. Jackets can be PTFE, FEP, ETFE or Varnished Fibre Glass (VFG), for high temperature requirements. Since PTFE jackets on large sized multi-core cables are extremely difficult, PVC or PU jackets are sometimes used."Our wires meet airworthiness requirement as well." "Standard cables meet popular military standards (US Navy's MIL-W-27500H, Indian JSS 51038) while custom cables can be designed according to the requirement. Our cables meet airworthiness requirement as well."

We refer to a case where we manufactured a special cable for British Nuclear Energy to control a Nuclear Robotic Arm. This cable had 28 members, some for sensing temperature, some for audio signals, some for video signals, a few for operating the lights inside the reactor, a number of others for activating the motor, and so on. Even though most common cables would not have such a large number of applications in a single construction, it is sufficient to illustrate the varied uses of multi-core cables.

Please contact us for any custom cable requirements.

GARG Advantages

• Evaluation of design and supply of technical data such as OD and weight/meter
• Can meet stringent requirement of twist/inch which affect common mode rejection ratio (CMRR)
• Wire of Insulation ratings up to 2500 V AC can be embedded in a multi core cable
• High-reliability in high-temperature interconnections for signal and control applications
• Production of Small lengths ( e.g. 50 meter) of complex cables are our specialty
• Experience in producing a great variety of multi-core cables ranging from shielded twisted pairs of AWG 34 to AWG 12
• Versatile equipment to produce multiple kind of shields (foil, braid, served) in a single cable
• Complete test report including capacitance data can be provided

How to select

• Conductor Selection
• Insulation Selection
• Isolation and Shielding Requirement
• Cross talk requirements: Near End Cross Talk (NEXT) & Far End Cross Talk (FEXT)
• Mechanical considerations e.g. flex life, dimensions
• Working Environment

Advantages of PTFE as insulation Material

• Inert to practically all chemicals even at elevated temperatures
• Fire (flame) proof
• Smaller size, lighter weight and much higher reliability
• Excellent thermal stability for use from -60C to 260C
• Minimal shrinkage/deformation at soldering iron temperatures
• Reliability
