If you’re wondering, “What is covered line wire?” then you’ve come to the right place. Covered line wire is a type of electrical conductor that is used in secondary distribution lines. It is not electrically insulated and must be treated as a bare conductor when installed. Covered line wire is also known by different code words. Some examples of covered line wire include conventional polyethylene line wire, aluminum 1350-H19 conductors, 6201-T81 concentrically stranded conductors, and ACSR stranded aluminum conductors. Polyethylene, meanwhile, refers to a high-density, cross-linked polyethylene.
Protects secondary distribution lines
Covered line wire provides the same protection against damage as bare wires, but is often a better option when tree growth is a concern. Unlike bare wires, which are prone to corrosion, covered line wire is not subject to the corrosion and oxidation that can result from exposure to sunlight. Also, the nonmetal covering material reduces the chances of damage to wildlife. The advantages of covered line wire are obvious: reduced frequency of tree trimming, improved tree health, and protection from high-wind and other weather events.
Provides weather resistance
A better way to make line wires weather resistant is to cover them. The manufacturer of line wires developed a weather-resistant covering. Before, coverings were comparatively cheaper, and thus, their life cycle was reduced. Now, the improved covering is more expensive, but it lasts longer and is more effective in providing insulation. Below are some of the benefits of covered line wires:
It has a high level of abrasion and chemical resistance. Its strands are made of multiple 18-10Awg wires. The wire is covered in either high density polyethylene (HDPE) or cross-linked polyethylene (XLPE) insulation. This wire is suitable for outdoor and wet environments. Its resistance to corrosion makes it an excellent choice for these environments. If you’re installing line wire outdoors, consider this material for its durability.
Prevents accidental contact with un-insulated lines
While covered line wire provides some insulating protection for overhead lines, many people are still exposed to electrical shock if they come into contact with them. To avoid accidental contact, you should always keep your distance from power lines. For safety, always ground all energized equipment before working near them. If you have to work near power lines, check for state laws before you begin. If you are unsure about the standards in your area, ask the company you work for.
A covered line wire also helps to keep birds from coming into contact with un-insulated lines. You should install the equipment in such a way that it does not come in contact with the line’s un-insulated portion. A bird may be unable to reach the circuit’s insulator if it rests on an uncovered line, but the electrical current it generates is still powerful enough to kill or injure a human.
Meets international standards
The Aluminum Covered Line Wire is designed to meet international standards for electrical safety and reliability. This type of cable features an aluminum concentric-strand conductor and cross-linked polyethylene (XLPE) or high-density polyethylene (HDPE) insulation. Unlike its electrically-insulated counterpart, this cable provides insulation from weather conditions and prevents arcing or flashovers. The Aluminum Covered Line Wire is also available in various colors to match the existing decor of your home.
