Explanation and review XLPE
We’re going to examine the technical details, perks, structure, components, and manufacturing procedure of XLPE in this Article. Due to the similarities and proximity of fireproof wire and cable and fire alarm, we will also examine the technical specifications, methods of production, purchase, sale, and price of fireproof wire and cable.
The advanced electrical insulator XLPE or Cross-Linked Polyethylene is crucial in the fabrication of electric wires and cables. This material ensures the safe and efficient transmission of electrical energy due to its unique properties.
What is the meaning of XLPE?
First, it is important to determine what materials are used in fire alarm wire and cable. What’s the chemical makeup of these substances? XLPE is an acronym for cross-linked polyethylene.
Polyethylene has a straight-line structure, as we all know. Polyethylene’s atomic arrangement lacks chemical bonds, and when heated to a high temperature, it loses its shape and state. The chemical has been established.
This type of insulation has been used in many low-pressure power cables and control cables, and most importantly, medium-pressure and high-pressure cables, where PVC insulation is the necessary capability for these voltage levels. It doesn’t need to be used or changed.
Specifications for the shielded cable with XLPE insulation
The reduction of dielectric loss is one of the biggest advantages of fire alarm-shielded cable with XLPE insulation for medium and high voltage. The loss coefficient or reduction of dielectric strength is one-tenth of the strength of the dielectric paper or insulation, and also about 0.2 lower than the strength of the desired cable.
There is a constant dielectric strength of the XLPE cable against the total capacity. This makes the charging current and earth leakage current lower, which prevents sparking inside the cable.
Advantages of XLPE fireproof cable
- The superior electrical and physical properties of XLPE fireproof cables have always made them one of the best types of cables for the transmission and distribution of electric current.
- The fire alarm cable with high current carrying capacity.
- The XLPE fire alarm cables have excellent resistance to deformation under very high temperatures. They’re capable of surviving the upper limit even when temperatures average below 90 degrees Celsius, critical conditions below 130 degrees Celsius, and short circuits reach 250 degrees Celsius, thanks to this technology.
- Installation was easy.
- There are no height restrictions and the ability to install wherever needed.
- There is no need for a metal sheath
Fire-resistant XLPE cables generally don’t require a metal cover, preventing damage to insulation and cable covers from deteriorating or corroding.
The steps of making XLPE cable
It is necessary to use the most advanced technologies that are used for several layers of these cables in an environment without water penetration to make fire alarm cables with XLPE coating.
The raw materials for XLPE wire and cable
The raw materials of XLPE wire and cable are made up of aluminum, which has a specific resistance of 1.65 times that of copper, a specific weight of three times that of copper, and a price that’s lower than copper. They have negative effects on it, such as corrosion, and as a result of its oxidation, aluminum oxide is formed, which is a thermally insulating substance.
The tensile strength of aluminum and its adaptability to take on desired forms are less impressive than those of copper, which is why it’s less popular. The rapid rise in the value of copper has led to an increase in the use of aluminum in recent years.
The price of copper is much more expensive than aluminum, so they use aluminum cable to make the price of the cable more economical. The issue will be resolved if this cable is constructed by established guidelines.
Due to its reasonable price, lightweight, resistance to corrosion, and mechanical strength in the wire and cable industry, especially XLPE wire and cable, aluminum is widely used in overhead transmission lines. It’s aluminum.
Recent years have seen the addition of a thin layer of copper to aluminum wires to address the issues resulting from its susceptibility to environmental influences, such as humidity.
The aluminum wires with copper walls are called aluminum wires. The physical properties of aluminum conductors have improved, and the problems of previous aluminum conductors have been resolved.
The development of wire and cable production
The use of XLPE as an insulating material in the production of wires and cables has led to significant transformations in the power transmission sector. The electrical energy transmission process has been made safer by this material.
Use for high-voltage power transmission systems
XLPE is a particularly important electrical insulating material for the production of wires and cables used in high-voltage power transmission systems. High-voltage resistance and outstanding regulatory properties of this material aid in the performance of these devices.
The conclusion
The use of XLPE in the fabrication of wire and cables as an advanced electrical insulator has enabled the secure and efficient transfer of electrical energy. With its special features, this substance not only helps to improve the performance of power transmission systems but also in creating
