Teflon wire (fluorinated ethylene propylene copolymer) FEP insulated wire is a high-performance wire, known for its excellent electrical properties, high temperature resistance, chemical resistance, and low smoke and low toxicity. Below TST CABLES explains the characteristics, applications, technical explanations, and testing of FEP insulated wires, hoping to help friends who are interested in Teflon cable FEP insulated wires.
Overview of Teflon FEP insulated wires
Definition: Teflon FEP insulated wires refer to wires and cables that use Teflon FEP as insulating materials.
Features: Teflon FEP insulated wires have excellent electrical properties, high temperature resistance, chemical resistance, low smoke and low toxicity, and are suitable for a variety of harsh environments.
Standards: Common Teflon FEP insulated wire standards include UL1007 wire, UL1061 wire, UL1123 wire, etc. These standards specify the requirements for electrical properties, mechanical properties, and combustion properties of wires.
There are three common forms of FEP fluoroplastic wires: single-core wires, coaxial wires, and multi-core wires. The following are introduced separately:
- Multi-core wires: single-core wires or coaxial wires are twisted together to make multi-core wires. There are twisted pairs and non-twisted pairs, which are used for industrial computer control and automation instrument control respectively. For special occasions, such FEP fluoroplastic wires are also used for Category 5 and Category 5e wires, data transmission, audio and video transmission, etc.
- Coaxial wires: The inner conductor is a single or multi-strand copper lead (tinned copper silver copper wire), with a diameter of 1.25~1.6MM, and there are three insulation forms: A. Fluoroplastic insulation, with a thickness of 0.5~0.7MM, B. Fluoroplastic foam insulation, with a thickness of 2.5~3.0MM, C. Fluoroplastic and polyethylene combined insulation, that is, the inner layer is insulated with fluoroplastic and the outer layer is insulated with polyethylene, and the thickness of the fluoroplastic is 0.04~0.07MM. It is worth mentioning that the coaxial wires insulated by fluoroplastics and polyethylene combine the advantages of product performance and material cost, and are worthy of vigorous promotion. This type of wire is often used as a connecting wire for radio frequency wires and electronic equipment.
- Single-core wire: also known as high-temperature wire, its structure is that the inner conductor is a single or multi-strand copper wire (tinned copper wire), the outer diameter of the conductor is 0.4~2.0MM, the insulation is fluoroplastic, and the thickness of the insulation layer is 0.3~0.5MM. It is often used as aviation wires, wiring of electronic and electrical equipment, and lighting wires for special occasions.
