About Overhead Power Transmission Lines Construction

Overhead power lines are the infrastructure for electric power transmission and distribution along large distances. It consists of one or more conductors suspended by towers or utility poles. Since most of the insulation is provided by air, overhead power lines are generally the lowest-cost method of power transmission for large amounts of electric energy.

Transmission-class line construction is very specialized. Compared to distribution construction, structures are taller, spans are longer, conductors are larger/heavier/stiffer, and pulls are longer and can extend over steep and very uneven terrain. In addition, aluminum conductors vary in construction requirements, calling for special handling techniques, tools, and equipment.

Transmission construction also involves different line and structure designs, as well as different conductor configurations (including simultaneous stringing of multiple conductors ('bundles") using a single pulling line). These configurations can range from single to bundles of two, three, four, and six conductors per phase. Some lines are strung using conventional, ground-based equipment and tools, while others require stringing using helicopters. 

Nowadays the great challenge is to increase the transmission efficiency and the transmission distance. Nanyue technology can help reaching these goals, thanks to its low conductor damage and multiple conductor machines and the capability of stringing any type of new generation conductor.

About Optical Ground Wire(OPGW)

Optical ground wire (OPGW) is a type of cable used in the construction of electric power transmission and distribution lines. This cable combines grounding and data transmission functions.
The OPGW cable are located at the ends of high-voltage pylons: its conductive part serves to bond adjacent towers to earth ground and shields the high-voltage conductors from lightning strikes. The optical fibers within the cable can be used for high-speed data transmission.
Nanyue is largely experienced in the installation of OPGW cables and this knowledge has been applied on a range of high performance machines.

About Reconductoring

Power transmission owners and operators need to develop solutions to maintain the transmission efficiency over time or to increase the capacity of existing lines, that are acceptable to the public, reliable and economical. Reconductoring is the key: renewing the old conductor (line refurbishment) or replacing standard conductors with those of last generation (line improvement).
Long lead times for new lines, limited availability of right-of-way and increasingly complex procedures for applications and permits justify the increasing attention in lines improvement and consequently reconductoring operations.
Nanyue has a great experience in reconductoring operations, especially in the installation of new generation conductors.

About Underground Cables Laying Installation

Communication, electricity and transport lines often require the installation of underground cables in order to obtain high-level performance and low impact on the environment. Underground cables need stringing equipment capable of operating under any condition, always providing good performance, high power and working accuracy. Nanyue stringing machines and accessories to install underground cables are designed and built to ensure the highest performance in terms of quality and resistance.
