Insulated wire is a type of wire that is uniformly and tightly wrapped with a layer of non-conductive material around the periphery of the conductor. It is mainly used to prevent accidents such as leakage, short circuit, and electric shock caused by contact between the conductor and the outside world. The insulation layer of insulated wires is usually made of materials such as resin, plastic, silicone rubber, PVC, etc., which have good insulation properties and can ensure the safe use of the wires.
Insulated wires can be classified into various types based on their purpose and structure, including plastic insulated wires, chloroprene rubber insulated wires, overhead insulated wires, adhesive impregnated low insulation power wires, polyvinyl chloride insulated and sheathed power wires, and rubber insulated power wires. Each type of wire has its specific application scenarios and performance characteristics. For example, plastic insulated wires are suitable for exposed installation or conduit use due to their good insulation performance and lower cost; Chlorinated rubber insulated wires have good oil resistance and are suitable for outdoor installation; Overhead insulated power lines are mainly used in places with high groundwater levels or chemical corrosive liquids overflowing.
different types of insulated wires have different models and uses:
1. Polyvinyl chloride insulated copper and aluminum core wires: used for indoor lighting and power line laying with rated AC/DC voltage of 500V and below, as well as outdoor wall support line installation.
2. Bare aluminum stranded wire and steel core aluminum stranded wire: suitable for outdoor high and low voltage overhead lines, especially in harsh weather conditions or high voltage situations.
3. Copper core rubber wire and aluminum core rubber wire: used for indoor lighting and power line laying with rated AC/DC voltage of 500V and below.
4. Polyvinyl chloride insulated flexible wire: suitable for infrequent power connections, but cannot be used for laying wires that are not fixed or in active environments.
5. Chloroprene rubber sheathed flexible wire: used as a power connection wire for mobile appliances or a power feeder for short-term temporary power transmission.
6. Polyvinyl chloride insulated and sheathed power wires: simple process, no height difference limit for laying, light weight, good bending performance, suitable for laying indoor and outdoor lighting and small capacity power lines.
These wires play an important role in power transmission, equipment connection, and other aspects, ensuring the safe and stable operation of the electrical system.
