1. Introduction

With the rapid development of optical communications, the amount of optical fiber loose tube cable for outdoor has increased rapidly. However, the capacity of the optical fiber in the loose tube is limited and it is impossible to make the loose tube large. In addition, in order to facilitate the connection identification of optical fibers and the distribution of optical nodes, the number of optical fibers in every loose tube should not be too large. For large-capacity communication requirements, the loose tube can only be twisted into cables according to certain rule.
The stranding of optical fiber cable can increase the number of optical fiber cores to meet the requirements of large-capacity communication. After the loose tube is twisted at a certain pitch, its cable core structure will become very stable, which is helpful for future construction. Because the loose tube is twisted according to a certain spiral angle, the soft performance of the cable is improved. Due to the stranding, the loose tube has a certain stranding radius, which increases the excess length of the optical fiber compared to the optical fiber and improves the environmental resistance of the optical cable.
At present, there are SZ stranding method and one-way (S or Z) stranding method for fiber optic cable. Because SZ stranding has the effect of canceling the stress of cable formation, SZ stranding is mainly used at present.
The so-called SZ stranding is when the stranding element reaches the specified S direction (or Z direction) number of twisted revolutions along the longitudinal axis of the optical fiber cable, and then reverse direction to stranding the same S direction ( Or Z direction) twisting numbers along the Z direction (or S direction). After the same number of turns of twisting, the twisting form of another twisting cycle is restarted. The quality of the SZ stranding process directly affects the performance of the finished optical fiber cable.
The realization of the SZ stranding process is completed by the SZ stranding line. Our company has many years of experience in the research and development of optical fiber cable production equipment. The SZ stranding line can be used for stranding (1~12) core optical fiber loose tube with fast production speed, high production efficiency, stable stranding pitch and other characteristics.

Q: Can I visit your factory?

A: All the customers from both home and abroad are warmly welcomed to visit our company and factory.

Q: Do you supply the installation and commissioning?
A: Yes, we do as followings:
-As soon as customer informed us the machines are put in the right place, we will send both mechanical and electrical engineer for machine start up.
-No-load testing: After machine installed completely, we make no-load testing first.
-With-load testing: Usually we will can produce 3 different wires to make load testing.

-Acceptance report: After the buyer confirms that machine can reach all specification under contract, the acceptance report will be signed for our record that machine will be in guarantee period.

Q: What information should I offer to get a detailed quotation from you?
A: For single machine: Usually we need to know inlet wire size, outlet wire size to be produced, productivity, pay off and take up size to choose the right machine.
For new cable plant or new cable production line, we need to know the datasheet of cables to be produced, the productivity, the standards to be followed, etc to design all machines needed.

Q: Can you supply the auxiliary equipment along with the machines?
A: Yes, definitely.
We has supplied heat exchanger, copper/aluminum powder filter machine, cooling tower, chiller, air compressor, drawing dies, pointing machine, cold welders, bobbins etc. with our machines.

Q: Could you do the design for the whole plant?
A: Yes, this is our advantage.
With the data sheet of cable to be produced, the standard your cables should follows, the productivity you expected. Our engineer on production technology and machinery will make design of production machines, test equipment, accessories like bobbins, dies, rewinding lines and materials needed.

Q: How can I know the status of my order?
A: We have our OA system on tracking the production.
For any of your request we can send photos and videos of your order, also we can use FACETIME to let you know the production.

Q: How do you work on the inspection before delivery?
A: We will make dynamic balance testing, levelness testing, noise testing, etc. during production.
After production finished, usually we make no-load running of each machine before delivery. Customers are welcomed to attend the inspection.

Q: What exhibitions will you attend, can we meet in the fair?
A: Dusseldorf International Wire and Cable Fair;
Wire South America Fair;
International Wire and Cable Fair in Shanghai;
International Istanbul Wire Fair, etc.
wire Southeast Asia Fair, etc.
