Galvanized steel strand is made of 7,19 or 37 wire galvanized steel wire, It’s usually use for steel core for stay wire or guy wire. It is widely used for transmission poles and railway track signals, And they can also be used in the aerial transmission line as the line material of ground connection to avoid the lightning strike.
The products applies to the lines for medium voltage aerial insulated cable for overhead power distribution lines, These lines can be found in many installations, such as in power plants, residential areas and mining operations, suitable for use in both dry and wet locations..admissible long-term operating temperature for conductor of cable for XLPE insulation, not exceed 90℃.
HDBS is made of 7,19 or 37 wire Hard Drawn Bare Copper wire, Used for overhead distribution lines, ground substations and system, and other electrical system.
Aluminum-Clad Steel Wire Strand Conductor is a bimetallic wire which steel wire is covered by Aluminum evenly with advantages of good. electric conductivity, anti corrosion, good high frequency transmission and high intensity. Aluminum-coated steel core aluminum stranded wire is a stranded wire which strands Aluminum-Clad Steel wire as reinforce core with aluminum wire. It is widely used for electric transmission line conductors, especially for coastal areas, salt alkali beach, grade 3 or grade 4 polluted industrial zone and the place with requirement of enlarged Aluminum steel cross-section ratio.
The aluminum conductor aluminum alloy reinforced(ACAR) is an excellent conductor choice where current carrying capacity, higher strength and a lower conductor weight are critical to the line design. The DC resistance of ACAR is smaller than ACSR, It is mainly used for electric distribution lines with little span, less stress. It has high current carrying capacity and better corrosion performance.
AAC has been widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity , And they are also suitable for laying across rivers valleys and the places where special geographical features exist. It is mainly used for electric distribution lines with little span, less stress. Temperature for continuous use is up to 75 ℃.
AAAC has been widely used in transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist. Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy have higher resistance to corrosion than ACSR.
