Single Core Cable Construction consists of:
Conductor
Conductor is a flexible wire type using metal materials. It is made of copper and coated with tin metal to prevent oxide formation and prevent resistance inside the conductor.
Insulation
Insulation made of XLPO (Cross-linked Polyolefin) prevents electricity from flowing only in the conductor and does not leak to other parts, which will cause hazards such as leakage or short circuit. Made of polymer plastic with high electrical resistance It is encapsulated on the conductor with the appropriate thickness so that it can support the voltage according to the rated voltage of the line. There are many types of insulation materials, each with different properties and the material that ZTT produces is Cross-Linked Polyolefin (XLPO).
XLPO insulation is produced by making polyolefin, which is thermoplastic, a chemical reaction transformed into a cross-linked which is stronger and more heat-resistant.
Sheath
Sheath (shell) made of XLPO (Cross-linked Polyolefin) is the outermost part of the electrical cable. It protects electrical wires from environmental conditions such as abrasion during installation, shock pressure, etc. sunlight It also has flame retardant properties. Low smoke and halogen emissions when exposed to fire.
Irradiation Cross-Linking is a radiation exposure process used to modify the polymer structure for cable insulation, enhancing its efficiency and resilience to environmental conditions such as fluid temperatures, pressure, and various operational states. This process increases the polymer’s flexibility, extends its lifespan, and allows for the production of insulation with smaller diameters.
The polymer structure is formed by molecules of carbon and hydrogen bonded together in long chains. Typically, the polymer used for cable insulation is Polyethylene, composed of carbon atoms and two hydrogen atoms (CH2).
When exposed to elevated temperatures, the polymer’s bonding in Polyethylene becomes more pliable, and it can melt. Similarly, operating in low-temperature conditions can alter material properties such as flexibility and strength.
Therefore, Irradiation Cross-Linking helps improve the efficiency and enhance various properties of the material, enabling it to perform better in different temperature conditions.
Chemical Vulcanization (CV / Continuous Vulcanization)
This method involves the use of chemicals to induce chemical reactions within the polymer structure, creating heat and pressure to transform the molecular structure of the polymer. A significant drawback of the chemical vulcanization process is the formation of by-products, such as peroxides, which can remain in the polymer. This leads to a reduction in insulating properties and a shorter lifespan. Polymers cross-linked using chemical vulcanization are limited to operating temperatures not exceeding 150 degrees Celsius.
Additionally, there is a risk of material twisting after the manufacturing process, especially in cable production, where it is necessary to use paper insulators to prevent adhesion between the conductor and insulation.
Irradiation Cross-Linking
Irradiation is a process that does not involve heat, pressure, steam, or chemical peroxides. This method avoids the drawbacks associated with chemical vulcanization, as it does not introduce by-products that could affect insulation properties. The irradiation cross-linking process provides greater flexibility in material applications and eliminates the need for paper insulation between the conductor and insulation in cable production. This method allows for a wider range of material uses and avoids the twisting issues associated with chemical vulcanization.
Irradiation Cross-Linking is a process that utilizes an electron beam generator to shoot electron currents into the polymer, displacing hydrogen atoms from their positions in the hydrogen-carbon chains of the polymer. This aims to allow direct bonding reactions (C-C) between carbon atoms of the polymer, forming a tightly linked molecular structure known as cross-links. These cross-links create strong intermolecular bonds, as illustrated in the accompanying diagram.
This process transforms the material from a thermoplastic (meltable) substance into a thermoset (non-meltable) material, significantly enhancing its performance and durability. This transformation is crucial in the manufacturing of electrical wires and cables to improve their operational efficiency and resistance. The irradiation cross-linking method strengthens the material by creating a network of cross-links, preventing it from melting and thereby enhancing its overall reliability in various applications.
