About Hengtian cable factory


1. How many years has Henan Hengtian Special Cable Group been in production?
Founded in October 1998 by Mr. Zhang, our facipty has three separate manufacturing workshops within its 300,000-sq.-ft. building. In 2012, we operates in a new 666,000 sq. foot state-of-the-art facipty in Xin'gang Industry Park.,zhengzhou, Henan ,China.
 
2. What kinds of products does Hengtian 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?

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