What are the main categories of electrical cables and wires?

Electrical wiring and cable products are mainly divided into the following categories:

Bare wires and bare conductor products:

Main characteristics: pure metal conductor, without insulation or sheathing.
Common products: steel cores with aluminum conductors, copper and aluminum busbars, wires for electric locomotives, etc.
Main application: mainly used in suburbs, rural areas, trunk lines, distribution cabinets, etc.
Electrical wiring:

Main characteristics: an insulating layer applied to the outer surface of the conductor, or several twisted cores, which may be supplemented with a sheath.
Common products: air-insulated electrical wiring, air-insulated electrical wiring with two or more cores, electrical wiring with plastic/rubber coating, etc.
Main application: used for power transmission in power lines, distribution, transformation, and supply, withstands high currents and high voltages.
Electrical wiring for electrical equipment:

Main characteristics: wide variety of types and specifications, wide range of applications, operating voltage mainly 1 kV and below.
Common products: fire-resistant cables, cables with increased fire resistance, cables with low smoke generation and halogen-free/low smoke generation and low halogen content, cables with termite/rat protection, oil-resistant/cold-resistant/heat-resistant/wear-resistant cables, cables for medical/agricultural/mining applications, etc.
Main application: widely used in various electrical devices, meeting the needs of special cases.
Communication cables and fiber optics:

Main characteristics: small and uniform dimensions, high manufacturing precision.
Common products: telephone cables, coaxial cables, fiber optic cables, data transmission cables, combined communication cables, etc.
Main application: used in the telecommunications industry to meet the needs of telephone communication, telegraph, data transmission, etc.
Electromagnetic wires:

Main application: mainly used in the windings of various electric motors, devices, and tools.
These classifications cover the main types and applications of electrical wires and cables. With the development of technology and changing application requirements, electrical wires and cables are also constantly evolving and improving.

-What cables are typically used for outdoor installation?

Cables with polyethylene or polyvinyl chloride insulation are typically used for outdoor cables.

A detailed explanation is provided below:

I. Types of cables

The selection of outdoor cables must be made taking into account various factors, such as operating conditions, climatic conditions, and data transmission requirements. Among them, cables with polyethylene and polyvinyl chloride insulation are the most common types of outdoor cables. These cables have good weather resistance and water resistance, allowing them to adapt to changing environmental conditions.

II. Characteristics of cables with polyethylene insulation

Cables with polyethylene insulation have excellent electrical and mechanical characteristics, and the insulation material has good weather resistance and resistance to aging. In addition, polyethylene cables are lightweight, simple in design, and relatively inexpensive, which allows them to be widely used in areas such as power engineering and communications.

III. Features of polyvinyl chloride insulated cables

Polyvinyl chloride insulated cables have good insulating, water-resistant, and oil-resistant properties and are able to adapt to complex and changing outdoor conditions. At the same time, cables with polyvinyl chloride insulation have good fire-resistant properties, which reduces the likelihood of fires. In addition, cables with polyvinyl chloride insulation are highly resistant to interference, provide stable signal transmission, and are suitable for communication and data transmission.

IV. Other factors to consider

When selecting a cable for outdoor installation, factors such as the cable's rated voltage, conductor material, sheath structure, etc. must be taken into account. In addition, cable products that have undergone professional certification and are of reliable quality should be selected to ensure safety, stability, and durability of operation.

In general, cables with polyethylene or polyvinyl chloride insulation are commonly used for outdoor cables. Both types of cables have good weather resistance and waterproofing, allowing them to adapt to changing outdoor conditions. When selecting outdoor cables, various factors must be taken into account to ensure the safety, stability, and durability of the cables.
