Overhead Transmission Line Cable

Conductor(AAC and ACSR) have 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.

2. Service Performance

(1). The permissible long-time operating temperature for aerial conductor is 70oC.

(2). Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area, the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.

(3). When connecting conductors, the conductor beside the connecting tube cant be prominent. Otherwise, the force on the operating conductors will be unbalanced. After connectors are install, the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.

(4). Under installaion, the arc downing stress of all the conductors should be the same. With in the permissible distance of crossing buildings or dropping to the ground, the stress can be 10-15% higher than regular stress.

3. Product Performance

(1). The electrical performance of AAC and ACSR is indicated in DCΩ /km(20oC). The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 nΩ . M of international standard value.

(2). The rated tensile strength of AAC is denoted with the result of total cross-section of all aluminum conductors multiplied by min. Tensile of corresponding size specified in the standard for aluminum wire.

(3). The rated tensile strengh of ACSR is denoted with sum of all aluminum conductorstensile strength and steels tensile strength.
A. The tensile strength of all aluminum conductors is denoted with the result of all cross-sections of aluminum conductors multiplied by min. Tensile strength of corresponding size specified in the standard for aluminum wire.

B. The tensile strength of all steel wire is denoted with the result of all cross-sections of steel wires multiplied by the stress at 1% elongation of corresponding size specified in the standard for steel wire.

4. Material Standard

(1). The hard aluminum conductor used for AAC and ACSR conforms to the standard GB/T 17048-1997(equivalent to IEC 60889: 1987).

(2). The zinc coated steel wire used for ACSR conforms to IEC 60888: 1987.

(3). Production can be arranged according to customers requirements for material standard, etc.

Founded in October 1998 by Mr. Gu, our facility has three separate manufacturing workshops within its 100,000-sq.-ft. building. In 2012, we operates in a new 666,000 sq. foot state-of-the-art facility in Xiaodian Industry Park.,Xinxiang, Henan ,China

2. What kinds of products does Jiapu Cable manufacture?
1)Bare Conductor ,such as AAC,AAAC,ACSR,ACAR,AACSR,ACSR/AW and so on;
2)Aerial Bundled Cable (1kV-35kV ),such as Duplex,Triplex,Quadruplex Drop Wires and so on;
3)PVC Insulated (Flexible ) Wire ;
4) PVC Insulated and Sheathed (Armoured) Power Cable;
5)Low, Medium, High Voltage (1kV-220kV) XLPE Insulated (Armoured) Power Cable;
6)Welding Cable, Control Cable, Concentric Cable, Rubber Sheathed Cable and so on;

3. What kind of certifications do you have?
SABS, CE, ISO9001-2000, SGS

4.Which markets do you involve mainly in?
Our products have been exported mainly to Africa, Middle East, South-east Asia, South America,Central America,North America, Europe ,Australia, etc.

5. Which standards do you comply with when you produce the electrical wires and cables ?
We are able to produce electrical wires and cables based on GB, JB, IEC, BS, DIN, ASTM, JIS, NF, AS/NZS, CSA, etc. Meanwhile, we can design and manufacture the cables according to the samples and technical specification the customer supply.

6. What is the min.order quantity ?
It depends on the type and size of electrical wires and cables. For some small electrical wires, 100 meters can be accepted .But for the power cables with medium or high voltage, that should comply with the property of installed equipments. Anyhow,we will try our best to solve the problem and meet with the requirement If you have special request.

7. What is the production capacity per week or per month ?
For the bare conductor, we can finish 3000 tons within one month. For power cables, that depends on the type and size. The total output value per month is approx. USD3,000,000.00 for insulated aluminum cables and that is approx. USD8,000,000.00 for insulated copper cables.

8. Do you supply the customers with installation service in foreign country ?
We don’t have professional installation teams in foreign country.But if that is necessary, we will recommend our partners to cooperate with you.
