Advantages of overhead insulated conductors:

Good insulation performance. Due to the addition of an 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 line supports, and increase the number of circuits installed on the same pole.

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.

Prevent external damage, reduce the influence of external factors such as trees, flying objects, metal films, and dust, and minimize phase to phase short circuits and grounding accidents.

The strength meets the requirements. Although the insulated wire lacks a steel core, it is tough and makes the mechanical strength of the entire wire meet the requirements of stress design.

Characteristics of using overhead insulated conductors:

1. Rated voltage: 0.6/1KV, 10KV;

2. The long-term allowable working temperature for cables is 70 ℃ for PVC insulation and 90 ℃ for cross-linked polyethylene insulation.

3. When short circuited (maximum time not exceeding 5 seconds), the temperature of the cable is 160 ℃ for PVC insulation, 150 ℃ for high-density polyethylene insulation, and 250 ℃ for cross-linked polyethylene insulation;

4. The ambient temperature during cable laying shall not be lower than -20 ℃;

5. Allowable bending radius of cable:

(1) Cables with a rated voltage below 1KV: For cables with an outer diameter (D) less than 25mm, it should not be less than 4D, and for cables with an outer diameter (D) of 25mm or more, it should not be less than 6D;

(2) The rated voltage of 10KV cable should not be less than 20 (D+d). In the formula: D-actual outer diameter of the cable, d-actual outer diameter of the cable conductor.

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.
