1. Basic classification of wires
Wires, as the key carrier of power transmission, have many classification methods.
1)Classification by material:
Copper core wire: Good conductivity, second only to silver, commonly used in home circuits such as BV wire. High mechanical strength, resistance to pulling and bending, good corrosion resistance, and long service life. HONGZHOUCABLE 12 Thhn stranded wire and 10 gauge 100 feet are very suitable for complex wiring, home and other scenarios.
Aluminum core wire: Low cost, used for large-scale power transmission. The conductivity is about 60% of copper, the mechanical strength is weak, it is easy to deform, and the aluminum oxide layer will affect the conductivity.
Iron core wire: used in special occasions where the conductivity is not high but the strength is required. Due to the high resistance and high energy consumption, it is rarely used in power transmission.
2)Classification by insulation material:
Polyvinyl chloride (PVC) insulated wire: good insulation, can prevent current leakage, chemical corrosion resistance, easy processing, various colors, easy to distinguish the purpose.
Cross-linked polyethylene (XLPE) insulated wire: insulation and heat resistance are better than PVC, can withstand higher voltage, suitable for large buildings and high-temperature industrial environments, anti-aging, long life.
Rubber insulated wire: good flexibility and wear resistance, suitable for places that need to be moved or easily rubbed, such as portable appliance power cords.
3)Classification by use:
Power cable: used for power transmission from power plants and substations to users, with high voltage levels, complex structures, and multiple layers of protection to ensure safe and efficient transmission.
Control cable: transmits control signals, such as automation and elevator control systems, with many cores, such as elevator control requires the transmission of multiple signals.
Communication cable: transmits telephone and network signals, and is divided into multiple types according to signal type and bandwidth, such as twisted pair for network and coaxial cable for cable TV.
4)Classification by structure:
Single-core wire: one conductor plus insulation, simple structure, used for small current. THHN of hongzhoucable 1. Solid filaments belong to this type of high-quality wires.
Multi-core wires: two or more conductors, which can be of the same or different specifications, have good flexibility, and can transmit multiple signals or large currents, such as four-core wires in a three-phase four-wire system.
2. Common wire types
Different types of wires are suitable for different scenarios. The following are some common wire types:
1) BV wire
Features: The copper core has good conductivity, second only to silver, and can effectively reduce the loss during power transmission. The polyvinyl chloride insulation layer has good insulation performance and can prevent electric shock accidents.
Application scenarios: Widely used in home lighting lines, ordinary socket lines, etc., such as connecting indoor chandeliers, wall lamps, ordinary electrical sockets, etc.
2) BVV wire
Features: Similar to BV wire, it has good conductivity and insulation. An additional layer of polyvinyl chloride sheath further enhances the insulation performance and mechanical protection capabilities of the wire.
Application scenarios: Suitable for relatively humid environments or places with a certain risk of mechanical damage, and places that may be subject to slight collisions or friction.
3) BLV wire
Features: The cost of aluminum core is relatively low, which has advantages in some cost-sensitive power transmission scenarios.
Application scenarios: Commonly used in some overhead lines or temporary power lines that do not have particularly strict requirements on power loss.
4) YJV cable
Features: The insulation layer is cross-linked polyethylene (XLPE), which has excellent electrical properties and can withstand high voltages. It has good heat resistance and anti-aging properties and a long service life.
Application scenarios: Mainly used for medium and high voltage power transmission, and the cables between substations and community distribution rooms mostly use YJV cables.
5) KVV cable
Features: The insulation material is usually polyvinyl chloride, which can ensure the accurate transmission of control signals. There are many cores, and common specifications include 4 cores, 6 cores, 8 cores, etc., which can meet the needs of transmitting multiple control signals.
Application scenarios: widely used in automated production lines, elevator control systems and other occasions.
6) RVV cable
Features: The copper core conductor is soft and easy to bend and move. PVC insulation and sheath have good insulation performance and certain protection capabilities.
Application scenarios: Suitable for power connection of household appliances, power tools, instruments and meters and other equipment, as well as wiring of electrical equipment that needs to be moved frequently.
3. Installation and maintenance of wires
Wire installation
1)Preliminary preparation: Plan the wiring according to the building structure and the layout of electrical equipment, and draw the wiring diagram to mark the key positions. Select wires and auxiliary materials according to current, voltage, etc. Prepare tools such as electricians' knives and ensure they are available.
2)Installation process: When laying concealed, dig a groove to bury the wire tube, and use steel wire to guide the wire after fixing and sealing, and separate different circuits. For open laying, use wire troughs or wire clamps to fix the wires. Small-section wires are twisted, and large-section or high-requirement wires are welded or crimped. The wiring of sockets and switches follows the "left zero, right live, and grounding", the switch is connected to the live wire, and the panel is fixed.
Wire maintenance
1)Daily inspection: Check the insulation layer and connection of the wires. Check directly for open laying and check the surrounding of the wire tube for concealed laying. Avoid adverse environments, deal with accumulated water, and insulate wires near heat sources.
2)Cleaning and maintenance: Use dry cloth to clean open wires and wires in wire troughs, without wet cloth or corrosive cleaning agents. Apply insulation protective agent, and use sheaths for outdoor wires to prevent aging.
3)Troubleshooting: Overheating or fuse melting may be overloaded, calculate the current to judge, and reduce equipment or change the line if overloaded. After a short circuit trips, cut off the power supply to check the connection points, etc., use an insulation resistance meter to find the short circuit point and repair it.
