Insulated wires Manufacturers online

Insulated cables are electrical cables that contain one or more cores in which the conductors (copper, aluminum, etc.) are surrounded by a layer of insulation.

This insulation protects against electric shocks, short circuits and other electrical hazards. The insulation also protects against mechanical damage and prevents contact with other conductive materials.

Below you will find how insulated cables work, an overview of types, their use and their advantages:

How it works:

The insulation encases the conductors and prevents the current from escaping from the conductors, flowing into other conductors or conductive objects. It also ensures that the electrical signals or current are transmitted safely and efficiently.

Types of insulated cables:

• PVC insulated wires: Widely used, inexpensive, heat resistant and flexible.
• Rubber insulated cables: Flexible and resistant to abrasion and moisture.
• Teflon-insulated cables: Heat resistant and suitable for high temperatures.
• Coaxial cables: Specially insulated for high-frequency signals, e.g. in communication technology.

Use of insulated cables:

1. Household applications:
Power supply: Insulated cables are used in households to supply power to appliances, sockets, switches and lighting systems.
Extension cords consist of insulated wires used to provide temporary or flexible power to appliances in various areas.

2. Trade and industry:
In industrial facilities, insulated cables are used to safely supply power to machines, equipment and tools.
Insulated cables are essential for the internal wiring of control cabinets, which are used to control and distribute electrical energy.
In automation technology, insulated cables are used in sensors, actuators and control units.

3. Construction:
In electrical installations in buildings, insulated cables are used for the distribution of electricity in walls, floors and ceilings.
Insulated cables are used in building automation, door intercoms, alarm systems and other low-voltage circuits.

4. Telecommunications and data transmission:
Insulated conductors are an essential part of network cables such as Ethernet cables used for data transmission in computer networks.
Coaxial cables are used for the transmission of high-frequency signals, such as in cable television and antenna systems.

5. Vehicle and aircraft construction:
In vehicles, insulated cables are used to supply power to lighting, engine controls, audio and safety systems.
In the aerospace industry, special insulated cables are used to withstand extreme temperatures and vibrations.

6. Special applications:
Insulated wires with special insulation that is water and weather resistant are used for outdoor and underwater applications.
In medical technology, insulated cables are used in devices that are operated in sensitive environments and under strict safety requirements.

Advantages of insulated cables:

• Protection against electric shock and short circuits.
• Minimization of current losses and interference.
• Resistance to environmental influences such as moisture, heat and chemicals.
• Suitable for many applications and environments.

Insulated cables offer decisive advantages for the safe, efficient and versatile transportation of electricity and signals.

Here are the most important aspects to look out for when buying insulated cables:

When purchasing insulated conductors, it is important to consider several factors to ensure they meet the requirements of your application while providing safety and longevity.

• Make sure the wire is suitable for its intended use, such as household appliances, industrial machinery, vehicle wiring or network installations.
• For outdoor applications, you need cables with weatherproof or UV-resistant insulation.
• The cross-section (e.g. 1.5 mm², 2.5 mm²) determines how much current the cable can safely carry. Select the cross-section according to the electrical load of your application.
• Make sure that the cable is suitable for the voltage and current to be transmitted in order to avoid overheating and short circuits.
• PVC insulation: Widely used and inexpensive, but less resistant to heat and chemicals.
• Rubber insulation: More flexible and resistant to heat and chemicals, ideal for industrial applications.
• Silicone insulation: Heat-resistant and flexible, suitable for high temperatures or flexible applications.
• Teflon insulation: Very resistant to extreme temperatures and chemicals, often used in special applications.
• Make sure that the cables are certified according to relevant standards, e.g. VDE, UL, or CE. This ensures that the cables are safe and conform to standards.
• Choose cables that are flame-retardant or have other safety-relevant properties if this is required for your application.
• For moving parts or applications that require frequent movement, you should choose flexible cables with a small bending radius.
• Pay attention to the abrasion resistance and tensile strength of the cable, especially for applications that are subject to physical stress.
• Choose cables that are suitable for the temperatures they will be exposed to, both in operation and during installation.
• For applications that are exposed to aggressive chemicals, moisture or UV radiation, you should look for cables with special resistance.
• Make sure that the cables have been stored under suitable conditions to ensure quality.
• For large projects, practical packaging sizes or shapes (e.g. on spools) can be important to facilitate handling.

By considering these aspects, you will ensure that you choose insulated cables that are safe, efficient and suitable for your specific requirements.
