Aluminum clad steel wire1. Specifications

Aluminum clad steel manufacture of bare overhead conductor. We have obtained certificates of ISO9001, ISO14001

The reliable, uninterrupted transmission of electrical power is vital to the electric utility industry. Transmission lines carrying large blocks of power must be permanently protected against damage from lightning. Alumoweld overhead ground wires provide the best means of obtaining this protection. They combine conductivity, , and high strength--all of the properties necessary for such assurance.

The thick aluminum cladding on each wire offers optimum protection against atmospheric corrosion while providing the conductivity important in proper operation of protective relays. The high conductivity of Alumoweld strand also reduces the temperature rise of the static wire under fault current conditions.

2. Excellent Conductivity
Due to a thick aluminum cladding, Alumoweld overhead ground wire provides one-third the conductivity of an aluminum conductor of equal size, and several times the conductivity of steel. Each Alumoweld product is tested for resistivity, a practice not generally used for steel. This insures known electrical properties in Alumoweld overhead ground wires.

These properties are maintained throughout the life of the line, as contrasted to the properties of steel wires with other protective coatings which can deteriorate over time. Such deterioration further reduces the already low conductivity of steel overhead ground wires.

3. Effect of Short Circuit on Overhead Ground Wire
Assuming complete absorption of heat by the ground wire

4. 20 degree C, D.C. Resistant:
7 No. 8 AWG Alumoweld, .446 ohms/1,000 feet
3/8-inch steel, 1.140 ohms/1,000 feet

5. Temperature Coefficient of Resistance:
7 No. 8 AWG Alumoweld, .0036/degree C
3/8-inch steel, .0035/degree C

6. Strength Comparable to Steel
In addition to superior conductivity and corrosion resistance, Alumoweld strand also provides strength equal to or greater than other overhead ground wires. Figure 2 below compares the strength of Alumoweld to that of various grades of steel strand. Tensile strengths of the individual wires of the commonly used sizes of Alumoweld approach 200,000 pounds per square inch. When used in a strand for overhead ground wire, this high strength permits smaller sags, increased mid-span separations, and greater safety under storm loading conditions.

7. Light Weight
Directly related to strength and sag performance is the lighter weight of Alumoweld strand. Due to its thick cladding of aluminum, Alumoweld is 15 percent lighter than a steel strand of equivalent size. This lighter weight, combined with high strength, permits Alumoweld strand to be strung to the same sags as steel with correspondingly lower tensions and lower stresses on the towers or supporting structures.

Dear Sir or Madam:

Our aluminum clad steel wire is perfectly combined of aluminum and steel core, and there will be no flaking off during the heat treatment or mechanical workout. The aluminum clad steel wire is the best new bimetal wire instead of pure copper wire.

Product scope:

Diameter: from φ0.10mm toφ3.00mm

Product features:

shiny, excellent electrical conductivity, bearing being bended, good tensile strength, excellent welding and corrosion, light specific gravity, and saving resources of copper

Main application:   

Flexible coaxial cable, all kinds of audio and video cable, vehicle signal cable, network cable, and data transmission cables and so on. Tinned copper clad steel can be used in follow cable:  cable conductor, braiding and shielding, the single wire conductor and other conductors. Applicable to a variety of electronic components lead wire, such as capacitors, resistors and so on.

We look forward your reply.

Best regards
