Structural components of power cord
In general, AC power cord with UL certification are designed to carry current from a source in a utility or power utility to its consumer. They have good design, as a rule, for alternating current in 10-35 kV, but there are varieties that are common to transfer current in 220-330 kV. Such wires are connected to stationary or mobile installations.
Where do we use AC power cord with UL certification?
The structural components of a copper or aluminum power cord will vary significantly depending on what the wire is common for. However, there are such components that no product can do without:
conductors;
core insulation;
shell;
the outer covering, which is entrusted with protective functions.
Each AC power cord with UL certification has a common insulation. Similarly, we call it belt insulation. The design of power cords assumes from one to five conductors. The veins themselves can be round or triangular in shape, they can also be sectorial. There are models with a single wire or with multiple wires that form a core.
Where can you get AC power cord with UL certification?
In the cord, we replace them in parallel or twisted. The core class can be from 1st to 6th. Our company will offer you the supply of a power three-core or four-core cord (copper, aluminum) at low prices and in a short time.
Often there is a zero core in the cord, which takes on the role of the neutral conductor, as well as the grounding cord, which serves as protection against electricity leaks.
What features AC power cord with UL certification carries?
The two-core AC power cord with UL certification can come with a shield that reduces the influence of the electromagnetic field, and also makes the field around the current conductor symmetrical. Among other things, such a screen will make the wire more resistant to external influences and strengthen its insulation.
If there is a risk that the cord will be damaged due to external influences, it makes sense to use armored products. Modern armored power cords will successfully withstand:
exposure to termites, ants, rodents and other pests;
Moreover, accidental hits with a tool during repair and other work;
pinching, pinching, etc.
Types of power cords
In our company, you can buy different types of power electrical cords (flexible, with copper conductors of different sections, with PVC insulation, etc.) at an affordable cost. We have options in the assortment:
fire-resistant - not exposed to open fire;
Moreover, shielded - an additional foil shield is provided;
rubber - with additional rubberized protection;
Similarly, armored - with a durable shell;
with PVC insulation - suitable for buried ground;
Similarly, with plastic insulation - depends on the temperature of the environment and the required voltage;
with XLPE insulation.
You can purchase any required model from us. You can buy flexible, acoustic, spiral, fire-resistant, armored AC power cord with UL certification. Products can be underwater, buried or self-supporting, and the price will be one of the most profitable on the market.
Material and cross-section of AC power cord with UL certification
There are two types of material from which the conductors can be made - aluminum and copper. The cross-section of aluminum conductors is directly related to the number of wires that will form the core. The dependency is as follows:
with a cross section of up to 35mm 2(inclusive), the core comes by only one wire;
Moreover, with a cross section of up to 300mm 2, one or more wires are common;
With a cross section of 300-800mm 2, several wires are necessarily common.
If you need to purchase power wires for a battery or for outdoor laying with copper conductors at a manufacturer's price, it is important to know that the situation is different here than with aluminum.
Single-wire conductors can be with a cut area up to 16mm 2 , and multi-wire ones - 120-180mm 2 . With a cross-sectional area of 25-90mm 2, both one and several wires can be common.
It is worth knowing that the zero core has a smaller cross-sectional area. Such a core is located between others and is marked in blue under the condition of a three-phase current.
Advantages of copper power cord
Aluminum wires have one undeniable plus - they are available. Moreover, aluminum itself is a high-quality and cheap conductor that does an excellent job of all the functions assigned to it. Aluminum AC power cord with UL certification, as a rule, is common to create long power lines.
However, there are a number of reasons that indicate that copper wires are best for home networks.
The thing is that they:
- much more plastic and do not break when bending, like aluminum;
- Similarly, they do not melt and do not weaken, like aluminum, with increased contact resistance, are much more reliable;
- an armored power cord made of copper will withstand loads much higher than an aluminum one, since at the same cross-section it will have a lower resistivity and, as a result, a higher electrical conductivity.
Therefore, it is best to buy a power underground or ground copper wire with existing aluminum AC power cord with UL certification with a cross section of up to 16mm2 and replace the old cords. It is recommended to change products with a larger cross-section to copper wires, but it should be borne in mind that copper is more expensive than aluminum.
AC power cord with UL certification Specifications
The purpose of the wires and the peculiarities of their production will greatly affect the technical characteristics of the product. Power installation wire can differ in a number of parameters:
- the number of veins can be from one to five;
- core material - aluminum or copper;
- cross-sectional area of the core;
- type of wire insulation.
Depending on these characteristics, the voltage that the wire withstands, the temperature at which it retains its performance, and also the service life will depend.
How to choose high voltage AC power cord with UL certification?
We will be able to provide detailed advice on how to choose a high voltage power cord (with or without a cord inside), where the product is common, how much it costs and what its service life is. It is enough to call us and talk to a qualified specialist.
A professional will be able to provide information that such AC power cord with UL certification operate at temperatures from +50 to -50 degrees, and the service life, if common correctly, can be up to 30 years.
The maximum power cord flat or other type can withstand up to 330 kV voltages. There are varieties of cords for insulation that will depend on the type of insulation. Namely:
- paper - up to 35kV;
- rubber - up to 10kV;
- PVC - up to 6kV.
Conclusion AC power cord with UL certification
Depending on the purpose, in our catalog you can find brands of flexible multicore AC power cord with UL certification for laying in the ground, flame-retardant (fire-resistant), in armor and others.
It is worth choosing a product depending on what functions will be assigned to it. In order for the wire to serve for a long time, you need to pay attention to products that will be most suitable for the operating conditions.
