Application
A low-voltage cable is a type of power cable that is used for the transmission of low-voltage electrical energy. In the context of electrical engineering, low-voltage cables are defined as cables with a rated voltage below 1000V. They are utilised for the distribution and transmission of electrical power in a variety of settings, including residential, commercial, and industrial areas. Low-voltage cables are typically composed of conductors, insulation layers, sheaths, and other ancillary components. Their structures and materials are designed and manufactured in accordance with the specific requirements of the intended application and with reference to international standards. Low-voltage cables are employed extensively in the internal power distribution of buildings, factory production lines, household appliances and other fields, and constitute an indispensable component of modern power systems.

What is XLPE Cable
The designation "XLPE" refers to a specific type of cable insulation, namely cross-linked polyethylene. The cable comprises an insulation layer and other components, all of which are manufactured from cross-linked polyethylene. XLPE cables are employed extensively for the distribution and transmission of electrical power in a multitude of applications, due to their exceptional electrical, mechanical and thermal properties.
The principal characteristics of XLPE cables are as follows:
The insulation resistance is high. The XLPE insulation provides high insulation resistance, rendering it suitable for high-voltage applications.
Thermal stability is a key characteristic of XLPE cables, allowing them to withstand high temperatures without significant loss of performance. XLPE cables demonstrate excellent thermal stability, enabling them to operate at elevated temperatures without a notable decline in performance.
Chemical Resistance: XLPE insulation demonstrates resistance to a diverse range of chemical substances, rendering it a suitable material for deployment in harsh environments.
The dielectric loss is minimal. The low dielectric loss characteristic of XLPE cable facilitates efficient power transmission.
The material is impervious to moisture. XLPE insulation material is impervious to moisture and therefore suitable for deployment in outdoor and underground applications.
XLPE cable is frequently utilised in power distribution networks, industrial installations, underground wiring, and other applications that necessitate high-performance, durable insulation. They are renowned for their reliability, longevity and capacity to accommodate high electrical loads.
