A solid-core hookup wire consists of a single metal wire (usually tinned copper) conductor and an insulating material wrapping. Solid core hook up wire is commonly used for wiring electronic equipment, has high resistance to environmental changes, and is suitable for applications that require minimal signal loss or resistance.
Prototyping: Solid core hook up wire is often used on breadboard or protoboard because its single metal core allows it to be easily inserted into the slots of these devices and maintain its shape.
Model making: Solid core hook up wire is widely used in model making such as model airplanes, model cars, model ships, etc.
Home appliances and electronic equipment: This wire is used for the connection of various home appliances and electronic equipment, such as lamps, household appliances, electric heating equipment, instruments, televisions, small household appliances, etc.
Automotive repair and modification: In automotive repair and modification, solid core hook up wire is used in the electrical system of the vehicle, including automotive repair wires and spark plug wires.
Industrial and mechanical equipment: Solid core hook up wire is also used in general mechanical equipment, such as robots, control elevators, lifts, cranes, etc.
Audio/video systems: In audio and video systems, Solid core wires are used in power lines to reduce high-frequency harmonic pollution.
Communication equipment: solid core hook up wire is used for voice and data transmission, including analog telephone, ISDN, VoIP and Ethernet data transmission.
Outdoor applications: Due to its corrosion resistance and durability, solid core hook up wire is suitable for outdoor electrical applications.
Power supply and load applications: In power supply and load applications, solid core hook up wire is used in transformers, voltage regulators, uninterruptible power supply (UPS) systems, etc.
1. Solid core hook up wires are usually easier to handle and weld because they are a single thicker copper wire, which makes them more convenient when wiring and welding.
2. Solid core hook up wire consists of a single larger conductor, usually copper wire, which has high durability and resistance to bending, so it is suitable for permanent or semi-permanent wiring, such as wall mounting systems, outdoor use, etc.
3. Due to its larger conductor diameter, solid core hook up wire has lower DC resistance and lower sensitivity to high-frequency effects, which means that under the same conditions, signal transmission loss is smaller and longer cable lengths can be supported.
1. Solid core hook up wire is prone to breakage when repeatedly bent and stretched due to its inflexibility, which affects transmission performance and may cause electrical failure.
2. Due to its rigidity, solid core hook up wire is not suitable for applications that are frequently moved or require bending, such as portable devices or occasions where frequent setup and removal occur.
Insulation materials are one of the most important components of solid core hook up wire. The following are the types of common insulation materials and their advantages and disadvantages:
Advantages: PVC has good mechanical properties, water resistance and flame retardancy, and is suitable for general-purpose solid core hook up wire.
Disadvantages: PVC has poor oil and chemical resistance and is prone to aging at high temperatures.
Advantages: XLPE has excellent flame retardancy, heat resistance, oil resistance and creep resistance, is suitable for low-temperature environments, supports high-speed extrusion, and does not contain decabromodiphenylene oxide product specifications.
Disadvantages: High cost and complex processing due to its rigidity.
Advantages: PTFE and FEP have excellent chemical and temperature resistance and are suitable for harsh environments.
Disadvantages: Higher cost compared to traditional materials such as PVC or XLPE.
Advantages: Silicone has high dielectric breakdown strength and excellent flame retardancy and is suitable for high voltage cable insulation.
Disadvantages: Usually more expensive than PVC and XLPE and does not provide as strong mechanical protection as other materials.
The choice of insulation material should be based on application requirements, such as temperature, voltage, and the need to resist corrosion.
The heat resistance of PVC insulation is generally 70°C. PVC insulation has poor tolerance to short circuits and is easily softened at high temperatures, causing damage and breakdown of the insulation layer. Therefore, it is suitable for general environments where the temperature is not extreme. And, due to its easy aging under high temperature and short-circuit current thermal effects, it needs to be replaced regularly.
Cross-linked polyethylene (XLPE) has good heat resistance and can work for a long time in high temperature environment without obvious performance degradation. The long-term working temperature can reach 90℃ and the instantaneous short-circuit temperature can reach up to 250℃. In addition, XLPE also has excellent mechanical properties, chemical corrosion resistance and UV radiation resistance, which makes it perform well in complex working environments.
Fluoropolymers such as PTFE and FEP are suitable for ambient temperatures up to about 300°C and have excellent oil resistance, solvent resistance, mildew resistance, waterproof and flame retardant properties. These materials are generally more stable in extreme environments, such as high temperature and chemical corrosion environments.
In addition, different insulating materials have different dielectric strengths, which determines how much voltage they can withstand before breakdown. The voltage tolerance range of XLPE, PTFE and FEP and PVC is: PVC＜XLPE＜PTFE and FEP. This means that solid core hook up wire insulated with PTFE and FEP can withstand higher voltages without failure, up to about 600V.
The size of the solid core hook up wire should be selected according to actual needs to ensure that it can carry the required current and adapt to the installation environment. The cross-sectional area of the conductor is a key factor in determining its current carrying capacity, usually expressed in square millimeters (mm²). A larger cross-sectional area means that higher current can be carried, thereby reducing voltage drop and heating problems.
Common solid core hook up wire specifications include 1.5mm², 2.5mm², 4mm², 6mm², etc. These specifications are suitable for different application scenarios. For example, 1.5mm² is suitable for low current applications, while larger specifications such as 6mm² are used for high current transmission.
Common colors of solid core hook up wires are black, white, blue, red, green, yellow, orange and brown. These colors not only meet international standards, but are also more common in actual applications. There are significant differences in the application of solid core hook up wire colors in different countries or regions, and they need to be selected according to the regulations of their own country.
