1. Power system:
The wire and cable products selected by the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper power cables (fundamentally replaced by plastic power cables), rubber cables, overhead insulated cables), branch cables (replacing part of the busbar), magnet wires and electrical wires and cables for power equipment.
2. Information transmission system:
The wires and cables used in the information transmission system mainly include local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communications or other composite cables.
3. Mechanical equipment, instrumentation system:
This part is used in almost all other products except overhead bare wires, but the first is power cables, magnet wires, data cables, instrumentation cables, etc.
Wire and cable products are mainly divided into five categories:
1. Bare wires and bare conductor products:
The primary characteristics of this type of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper and aluminum busbar, electric locomotive line, etc.; The processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/pressing stranding, etc.; The products are mainly used in suburbs, rural areas, user mainlines, switch cabinets, etc.
2. Power cable:
The main characteristics of this type of product are: squeezing (winding) the insulating layer outside the conductor, such as overhead insulated cables, or several cores stranded (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulated cables with more than two cores, or adding a sheath layer, such as plastic/rubber sheathed wires and cables. The primary process technology is drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, sheath extrusion, etc., and there are certain differences in the combination of different processes of various products.
The product is mainly used in the transmission of strong electric energy in the power generation, distribution, transmission, transformation and power supply lines, and the current through it is large (tens of amperes to thousands of amperes) and high voltage (220V to 500kV and above).
3. Wires and cables for electrical equipment:
The main characteristics of this type of products are: a wide variety of specifications, a wide range of use, the use of voltage in 1kV and below more, in the face of special occasions continue to derive new products, such as fire-resistant cables, flame retardant cables, low-smoke halogen-free / low-smoke and low-halogen cables, termite-proof, anti-rat cables, oil-resistant / cold-resistant / temperature-resistant / wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc.
4. Communication cables and optical fibers:
With the rapid development of the communication profession in the past two decades, the products have also developed at an astonishing speed. From the simple telephone and telegraph cables in the past, it has developed into thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables.
The structural size of this type of product is usually small and uniform, and the production accuracy is high.
5. Magnet wire (winding wire):
It is mainly used in various motors, instruments, etc.
Derivatives/new products of wire and cable
The derivative/new products of wires and cables are mainly due to the requirements of different use occasions, different use requirements, convenience of equipment and reduced equipment costs, etc., and the selection of new materials, special materials, or changes in product structure, or progress process requirements, or the combination of different varieties of products.
Choose different materials such as flame retardant cables, low-smoke halogen-free/low-smoke and low-halogen cables, termite-proof, rodent-proof cables, oil-resistant/cold-resistant/temperature-resistant cables, etc.;
Change the product structure, such as: fire-resistant cable, etc.;
Advanced process requirements, such as: medical cables, etc.;
Combination products such as: OPGW, etc.;
Convenient device and drop equipped with cost, such as: prefabricated branch cables, etc.

Introduction to Schneider inverter inverter
The inch movement in Schneider inverter means that the control signal can drive the motor intermittently according to a certain law, and the motor strictly follows the dynamic and stop command action of the control signal, and the motor does not roll by inertia during the shutdown. It's like moving an inch and then stopping.
The full name of Schneider inverter is "...

The inverter controls the speed of the AC motor – Schneider
Most of the motors used in the industry are of this type. The rotational speed of an induction AC motor (henceforth referred to as a motor) is approximately determined by the number of poles and frequency of the motor. The number of poles of the motor is fixed by the working principle of the motor. Since the pole ...
