ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium. ACSR conductor is available in a range of steel strengths varying from 6% up to 40%. The higher strength ACSR conductors are used for river crossings, overhead earth wires, and installations involving extra long spans. Against any given resistance of conductor, ACSR conductor may be manufactured to have different tensile strengths as per requirement. The principal advantage of these conductors are their high tensile strength and light weight, covering longer spans with less supports. Due to the greater diameter of an ACSR conductor much higher corona limit can be obtained, giving a big advantage on high and extra high voltage overhead lines.
Standards:
ASTM - B 399 Metric Units
ASTM - B 231
TS IEC 1089
DIN 48201
BS 215
UNE 21.018
Key Benefits:
The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to the greater diameter of ACSR conductors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.
ACSR conductors consist of a solid or stranded steel core surrounded by strands of aluminum (E. C. GRADE). ACSR conductors are available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR conductors are used for river crossings, overhead ground wires, installations involving extra long spans etc. Against any given resistance of conductor, ACSR may be manufactured within a wide range of tensile strength as per the requirement.

Brief Introduction
PVC/XLPE power cable is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.
Standard
The products can be produced according to our factory specification which is equivalent to the standard IEC60502. The factory can also design and manufacture special power cable according to the other standards required by the customers.
Properties of PVC Power Cable
1. The long-time permissible working temperature of cable conductive core is not more than 70 degrees.
2. During short circuit (max permanent time is not more than 5 seconds), the max temperature of cable conductor is not more than 165° C.
3. The difference level of laying cable is not restricted. When laying the cable, ambient temperature is not lower than 0° C.
4. They have good chemical stability, and properties of acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance and flame resistance.
Properties of XLPE Power Cable
1. The highest allowed operating temperature of conductor for long-term working is 90 degrees.
2. In short circuit (Max long term is no more than 5 seconds). The highest temperature for conductor is no more than 250 degrees.
3. The cable is laid without horizontal drop limit. The environment temperature should be no lower than 0 when lay. Otherwise it should be preheated.
4. Excellent electrical performance, resistance to chemical corrosion.
5. Can stand advisable traction when laid. Can stand traction from Outside. Left low smoke halogen-free after burned. Retard the burning of the cable.
