Hook-Up Wire, also known as lead wire or appliance wire, is a single-core insulated cable mainly used for internal wiring of electronic equipment.
This is the core part of the hook up wire, responsible for transmitting current. Common conductor materials are copper and aluminum, among which copper is widely used due to its good conductivity and high mechanical strength. For example, UL1015 Hook-Up Wire uses tinned softened copper wire.
The function of the insulation of the Hook-Up Wire is to isolate the conductor from the ground and the conductors of different phases, ensure the effective transmission of electrical energy and prevent electrical short circuits.
Common materials for the insulation of the Hook-Up Wire are: PVC (Polyvinyl chloride), Silicone, Rubber, FEP (fluorinated ethylene propylene), PTFE (Polytetrafluoroethylene, commonly known as Teflon).
Good insulation can effectively prevent accidental leakage or short circuit between the cable sheath or the external environment, ensuring the safety of users and equipment.
Insulation also has the ability to resist environmental erosion. Cables may be installed in a variety of environments, including harsh conditions such as moisture and chemical contact. Insulation can resist the erosion of metal conductors by moisture, chemicals, etc., and extend the service life of cables.
Insulation of different materials has different heat resistance. Ordinary household wires are generally made of polyvinyl chloride (PVC), which has a rated operating temperature of 70-90 degrees Celsius and a molten state of 150 degrees Celsius. Some special high-temperature resistant wire varieties use materials such as PTFE or FEP, which enable them to adapt to overheating environments such as furnaces and ovens.
Although some types of Hook-Up Wire may not include a sheath, some products will add an additional layer of sheath to protect the cable from physical damage and environmental factors. The sheath material can be polyvinyl chloride, polyurethane or other wear-resistant, oil-resistant, acid-resistant and alkali-resistant materials.
For some specific applications, such as those that require electromagnetic interference resistance, a shielding layer may be added to the insulation. This shielding layer is usually made of metal mesh or metal tape to reduce the interference of external electromagnetic waves on the signal in the cable.
In the process of transmitting current, Hook-Up Wire mainly transfers electrons from one end to the other through metal bonds.
Metal bonds are similar to chemical bonds between molecules and are a manifestation of electromagnetic force, allowing electrons to move freely in the conductor.
When an external electric field is applied to the wire, these free electrons will drift under the action of the electric field, thereby realizing the transmission of current.
Hook-Up Wire is widely used in circuits, motors, transformers, distribution boards, and rectifiers. This wire is mainly used in low-voltage and low-current applications, such as internal wiring of enclosed electronic devices. It is also suitable for some projects that require high conductivity, such as automotive work and electronic projects.
Hook-Up Wire is particularly suitable for use in small spaces due to its flexibility and small size. It is usually used for internal wiring of electronic equipment, such as computers, TV receivers, heaters, ovens, dryers, etc.
Hook-Up Wire is also widely used in the military field and industrial automation, such as military bus bars and power transmission lines. These applications require wires to have high temperature, high pressure and oil resistance.
The Hook-Up Wire we are using now can have a service life of 50-70 years under ideal conditions. However, frequent use of high-power electrical appliances, long-term load power consumption, and high ambient temperature will shorten the life of the hook-up wire. Therefore, it needs to be replaced every 25-50 years depending on different usage conditions.
In addition, the hook-up wire needs to be replaced in the following situations:
Poor contact, overheating of the terminal interface, etc. during use
When the insulation is broken, worn, etc.
When the recommended replacement time of the merchant is reached
Exposure to moisture or corrosive chemicals
Several factors need to be considered when buying Hook-Up Wire:
Choose the appropriate Hook-Up Wire conductor and insulation material according to the use environment of the wire, such as temperature, humidity, chemical corrosion and other conditions.
Choose the appropriate specifications and models according to the actual power load, power environment and power consumption. The conductor cross-section or wire gauge and the maximum current (current carrying capacity) are the key parameters.
Purchase hook-up wire that meets national standards. These standards cover all aspects from design, manufacturing to installation and use.
Choose the appropriate length. The cable length calculation includes the actual path length and additional length, such as terrain height difference changes, expansion joints or detour reserve margins, etc.
Our main hook up wire products include FEP Hook Up Wire and PTFE Hook Up Wire. FEP Hook Up Wire is suitable for high temperature environments, has excellent chemical resistance, can work stably in the temperature range of -65°C to 250°C, can be encapsulated or bonded on the surface, and provides a full range of color options.
PTFE Hook Up Wire is widely used in automotive oxygen and NOx sensors, gas igniters in ovens and dryers, outdoor heaters, gas lamps and mosquito repellents, medical and scientific instruments, computers, aircraft and marine systems, etc. because it remains flexible under extreme conditions.
