Triple Insulated Wire (TIW) is a wire with three independent insulation layers, which is usually used in applications with high requirements for safety and electrical performance. Triple Insulated Wire is a high-performance insulated wire with three insulation layers and a core wire in the middle. The insulation thickness can be as low as a few microns. At the same time, due to the use of special coated conductors, low loss is compatible with high space coefficient, which can greatly reduce the volume of electrical equipment using this material, save materials, and significantly reduce costs. Especially for the motor and transformer industry, the reinforced insulation wire composed of three layers completely isolates the primary and secondary of the transformer. Therefore, it eliminates the barriers, interlayer tapes and insulating tubes in the transformer. In addition to reducing the size of the transformer and saving material costs, its performance can also be improved by reducing the distance between the coils.
Low-loss high-frequency triple insulated wire places special emphasis on low loss characteristics in high-frequency applications, which makes it very suitable for electronic equipment, communication equipment and other application scenarios that require high-efficiency transmission.
Characteristics of Triple Insulated Wire
High insulation strength: Triple insulation provides additional safety protection, ensuring effective prevention of electrical breakdown even under extreme conditions.
Excellent electrical properties: Maintaining low dielectric loss and stable capacitance at high frequencies helps reduce signal loss and improve transmission efficiency.
Heat resistance: Good temperature resistance is usually taken into account in material selection, allowing the cable to work stably over a wide temperature range.
Mechanical strength: In addition to electrical performance, it also has a certain mechanical strength to cope with the stress that may be encountered during installation and use.
Triple-layer insulated wire material
The core conductor of low-loss high-frequency triple-layer insulated wire is usually made of high-purity copper to reduce resistance and improve conduction efficiency. As for insulating materials, commonly used ones include:
Polyethylene (PE) or cross-linked polyethylene (XLPE): These materials are widely used in high-frequency applications due to their low dielectric constant and loss factor, which can effectively reduce signal attenuation.
Polytetrafluoroethylene (PTFE) or its copolymers such as FEP (fluorinated ethylene propylene): These fluoropolymers not only have excellent electrical properties, but also have excellent chemical stability and high temperature resistance, which are very suitable for high-frequency and high-power applications.
Application of three-layer insulated wire
This type of cable is mainly used in situations where signal integrity and reliability are high, such as:
High-frequency transformer
Switching power supply
Communication equipment
Medical equipment
Automotive electronic system
