Fluoroplastic Signal Cable: Ideal for the Challenges of Harsh High Temperature Environments

Fluoroplastics is a general term for a variety of fluoropolymers, which are polymers made by self-polymerization of monomers containing fluorine atoms or copolymerization with other non-fluorinated materials.

Fluoroplastics are suitable for use as wires and cables due to their excellent electrical properties, thermal stability and mechanical and physical properties. Fluoroplastics Cable, English name Fluoroplastics Cable, is used to refer to the wire and cable with fluoroplastics as the jacket.

I. Fluoroplastic signal cable performance characteristics

  1. Wide temperature characteristics and very high temperature resistance.

Fluorine plastic insulated wire can be -60 ~ 260 ℃ range of long-term continuous work, in 300 ℃ can also work for a short period of time.

  1. Excellent electrical properties.

Mainly characterized by high dielectric strength (up to 24KVmm), high volume resistance (up to 1018 level) and low dielectric loss (up to 10-5 level).

  1. dielectric constant and dielectric loss basically does not change with the frequency, temperature changes.

Often use this feature to produce radio frequency cable, this type of radio frequency cable can usually work in dozens of gigahertz frequency presents low loss.

  1. Oil-resistant, solvent-resistant, chemical-resistant and other chemical stability,so widely used in petroleum, chemical, aerospace, automotive and other industries.

II. High temperature fluoroplastic signal cable structure

According to the International Electrotechnical Commission standards IEC and UL standards, PTFE polytetrafluoroethylene (F4) insulated wire and cable structure is mainly:

Conductor: tin-plated, silver-plated, silver-plated or nickel-plated high-strength copper alloy wire and so on;

Insulation structure: a single PTFE polytetrafluoroethylene (F4) insulation extrusion structure; or PTFE polytetrafluoroethylene (F4) extrusion, plus impregnated with silane paint or TFE glass yarn braided combination structure, or mica tape wrapped around impregnated glass yarn braided combination structure.

III. High temperature fluorine plastic signal cable application

High temperature fluorine material signal cable is mainly used:

Due to the excellent performance of fluoropolymer insulated high temperature wire and cable, they have a wide range of applications in several fields:

Electric power, metallurgy, petroleum, chemical industry and other fields: in the infrastructure construction and high-temperature harsh environments of these industries, fluoropolymer insulated high-temperature wire and cable can work stably for a long time to meet the needs of complex electrical connections and automatic control systems.
Aviation, aerospace field: due to the special characteristics of thermoplastic fluoroplastics used in aviation cables, fluoropolymer insulated high temperature wire and cable is also widely used in aviation and aerospace fields, which can meet the requirements of high performance and high reliability of cables in these fields.
Other special applications: In addition, fluoropolymer insulated high temperature wire and cable is also used for RTD leads, thermocouple leads, installation lines in the motor industry, signal lines for analyzing instruments, extension lines for UV lamps, ground sensing lines for intelligent transportation, and high-temperature cables dedicated to the secondary side of current transformers in the power industry.
