　　Characteristics of overhead insulated lines:

　　 Overhead insulated lines, Aerial Insulation Line， An insulated wire made by twisting single or multiple layers of aluminum wire and extruding an insulation layer outside the wire. This type of wire is erected by a tower at a certain height to transmit power and is suitable for high and low voltage transmission and transformation overhead lines.

　　For the ground insulation of high-voltage transmission and distribution network overhead lines, air is generally used. In the past, distribution lines (except for 380V below 10kV) generally used bare wires. However, due to the complex distribution environment in urban areas, short-circuit grounding and lightning strikes often occur, resulting in reduced power supply reliability. Therefore, currently, insulated wires (i.e. the outer layer of the wire is wrapped with insulation) are generally used for overhead lines below 10kV, which is called insulated overhead lines.

　　There are two types of overhead lines: low voltage and high voltage, with and without internal screens. The models are JKLYJ and JKLGYJ. JKLYJ is an all aluminum overhead wire, while JKLGYJ is a steel core overhead insulated wire, which means there will be one or several steel wires twisted together in the middle of the aluminum core to resist tension.

　　JK represents overhead, L represents aluminum core, G represents steel core, and YJ represents cross-linked polyethylene.

　　1.1 Good insulation performance

　　Due to the additional insulation layer, overhead insulated conductors have superior insulation performance compared to bare conductors, which can reduce the distance between lines, lower the insulation requirements for supporting components, and increase the number of circuits installed on the same pole.

　　1.2 Good anti-corrosion performance

　　Due to the insulation layer on the outer layer, overhead insulated wires are less susceptible to oxidation and corrosion than bare wires, and have stronger corrosion resistance, which can extend the service life of the line.

　　1.3 Protection against external damage

　　Reduce the impact of external factors such as trees, floating metal film, and dust, and minimize phase to phase short circuits and grounding accidents.

　　Transportation precautions;

　　It is strictly prohibited to throw cables or cable reels containing cables from a height during transportation, especially at lower temperatures (usually around 5 ℃ or below). Throwing or dropping cables may cause insulation and sheath cracking. Try to avoid storing cables in an exposed manner outdoors as much as possible, and cable reels are not allowed to be laid flat. When lifting the packaging of the JKLYJ overhead line model, it is strictly prohibited to lift several reels at the same time. On vehicles, ships, and other transportation vehicles, cable reels should be secured using appropriate methods to prevent collisions or tipping over, in order to prevent mechanical damage to the cables. Cables must not come into contact with acids, alkalis, and mineral oils, and must be stored separately from these corrosive substances There shall be no harmful gases that damage insulation or corrode metals in the warehouse where cables are stored. During the storage period, the cable should be rolled regularly (once every 3 months in summer, and may be extended at discretion in other seasons). When rolling, roll the storage tray upside down to prevent the bottom from getting damp and rotting. When storing, it is important to regularly pay attention to whether the cable head is intact and undamaged.
