High voltage unarmored cable is a type of electrical cable that is designed to carry high voltage electricity without any armor or protective covering. These cables are typically used in applications where the cable is not exposed to physical damage or environmental hazards.
The construction of a high voltage unarmored cable typically includes a conductor, insulation, and an outer sheath. The conductor is usually made of copper or aluminum and is designed to carry high voltage electricity over long distances. The insulation is made of a high-quality material that is designed to withstand the high voltage and prevent any electrical leakage.
The outer sheath is typically made of a durable material such as PVC or polyethylene and is designed to protect the cable from moisture, chemicals, and other environmental hazards. Unlike armored cables, unarmored cables do not have any additional layers of protection, which makes them more flexible and easier to install.
High voltage unarmored cables are commonly used in applications such as power transmission, distribution, and industrial automation. They are also used in renewable energy applications such as wind and solar power generation.
