OPGW :   The Styles of the Products

The Styles of the Products Optical unit Central tube structure of OPGW Co-eccentric tube structure of OPGW

Central tube structure (single stranding)	Co-eccentric tube structure (double stranding)	Co-eccentric tube structure (triple stranding)
The stainless steel tube containing the optical fibers	Al-clad steel wire	aluminum alloy wire

In the structure there must not be the  plastic ingredients so as to increase its reliability and the performance of temperature tolerating. It is painted with the oil gel preventing from erosion(IEC61394) between the standing layers in order to guarantee utilization life. The Max. number of the optical fiber cores can be gotten in the case of the same cable diameter and optical fiber excess length The cable diameter is smallest under the condition of the same number of the optical fiber cores and the same mechanic and electric gas property There can be three optical fiber stainless steel tubes in the DA structure and TA structure at most so that it can increase the number of the optical fiber cores The proportion of the aluminum and the steel can be adjusted by the adjustment of the structure for the balance of the mechanic intensity and the value of the short circuit.
