Wire and cable are important industrial products for a wide range of applications.. ZMS provides you with technical information on all types of wire and cable.
Most electrical cables are made in the factory. So you should do some research before ordering.. If you want a wide range of high quality cables, look for a company specialized in the manufacture of cables.
If you need advice on the selection of different wires and cables and their technology, we can help you. When choosing a cable provider, You should consider the following factors.
Aerial cables are a way of installing lines for outdoor use, leaning on poles. Aerial cables are usually bare conductors with multiple stranded wires.
Due to the good heat dissipation conditions of the cable, its load capacity is between a 30 and a 40% greater than that of an insulated cable of the same section. This represents a significant reduction in the cost of the line.
It can be said that wire and cable play an indispensable role in the electrical and electronic industry.. Due to the characteristics of electrical cables, your storage, use and transportation must meet certain requirements to ensure the quality of the products and the safety of their use.
With the continuous development of rail transport, demand for railway cables is also growing. The scale of investment in rail transit construction is large, and involves many industries.
construction, metallurgy, electricity, communication signals, engineering machinery manufacturing and mechanical and electrical equipment manufacturing and many other industries can benefit from it.
solar cables, also known as cables PV, are the components of the solar system to connect the panels of the photovoltaic power system. Photovoltaic power generation is based on the principle of photovoltaic effect.
Uses solar cells to convert energy from sunlight directly into electricity. Photovoltaic power systems consist of three main components: solar panels, regulators and inverters.
Submarine communication cables are wires wrapped in insulating material. They are placed at the bottom of the sea to allow the transmission of telecommunications between countries.
The first submarine communication cables provided telegraphic communications. Later, telephone and Internet communications were introduced.. The modern fiber cable also uses fiber optic technology, so it is called submarine fiber optic cable.
Cables are the heart of any electrical project. Whether it is an interior or exterior project, an underground or aerial installation, cables are the key.
So, What type of the cable should we choose? Copper or aluminum cable? Does the cable need reinforcement? (usually steel)?
In this article we will explore these issues and explain why aluminum cables may be more suitable than other options for certain types of power transmission..
The power transmission by high-temperature superconductors is one of the most revolutionary engineering technologies in the energy industry today.
The term high-temperature superconductivity refers to the use of superconducting materials in an environment of liquid nitrogen a -200 Celsius degrees, near absolute zero.
In this case, the resistance of the energy transfer medium is close to zero and energy transfer losses are practically non-existent.
as a natural phenomenon, lightning is generated for various reasons. During the frequent annual lightning season, power lines can be significantly affected.
Las 10KV overhead lines are subject to direct and induced lightning, that can generate very high voltages and cause surges in overhead cables.
The lightning surge is usually much higher than the allowable voltage of the line. The lack of protection measures against lightning can easily cause it to strike the insulation., which can lead to fractures at weak points. Serious damage to electrical equipment leads to unnecessary safety accidents.
PVC cable material is manufactured from polyvinyl chloride as the base resin., to which stabilizers are added, lubricants and inorganic fillers. It is prepared by mixing, kneading and extruding.
Although this material has mediocre properties and is not environmentally friendly enough, it is less expensive and the process is simpler. So, PVC remains one of the most widely used cable materials.
