Covering prevents faults due to contact
Proprietary, high density outer layer resists abrasion and electrical tracking
High impulse strength allows for close spacing of phase conductors
Installed the same as bare conductors, however, covering is effective in preventing direct shorts and instantaneo
AAC (1350-H19), AAAC or ACSR conductors, concentrically stranded. Available with black or gray track resistant, high-density polyethylene (HD) or black track-resistant crosslinked polyethylene (XLP) covering. Covered conductors consist of stranded hard drawn aluminum conductors with either one, two or three extruded layers depending on the voltage rating.
In a Covered Aerial MV System (formerly called Spacer Cable), spacers hold three MV phase conductors in close approximation. The spacers are suspended from a high-strength messenger wire. Covered Aerial MV (CAMV) cable itself is a single aluminum conductor protected by a layer of track-resistant polyethylene.

Medium voltage surge arrester are electrical devices designed to protect electrical equipment from surges or transients that occur on medium-voltage power systems. These systems typically operate at voltages between 1kV and 36kV, and they are commonly found in various industries, such as manufacturing, oil and gas, and utilities.
Medium voltage surge arresters work by detecting and diverting excess voltage away from the equipment and toward the ground. They are typically composed of metal oxide varistors (MOV) or zener diodes, which provide a low resistance path to the ground during transient events. When a surge or transient occurs, the surge arrester conducts the excess energy to the ground, protecting the equipment from damage.
MV surge arrester are selected based on the specific application, voltage requirements, and surge current capacity. They are often installed in parallel with the equipment they are protecting, with a short path to the ground. Proper installation and maintenance are important to ensure the effectiveness of the medium voltage surge arrester.
Application of Medium Voltage Surge Arresters
surge arrester medium voltage are commonly used in a variety of applications, including power distribution systems, industrial facilities, and commercial buildings. They are installed to protect equipment such as transformers, switchgear, motors, and other medium voltage electrical components from voltage surges or transients caused by lightning, switching operations, or other sources.
Medium voltage surge arresters are also used for the protection of telecommunication networks, data centers, and other critical electronic equipment. They play a significant role in ensuring the safety and reliability of power systems, protecting equipment from damage, and reducing the risk of operational downtime. Proper selection, installation, and maintenance of medium voltage surge arresters are essential to their effective operation and long-term service life.
