N.J. International is a stringing equipment supplier since 2006. As a company specialized in the field of conductor stringing for overhead transmission lines, we have a distinctive understanding of the concerns and major challenges faced by our customers. Our years of field experience allow us to provide global customers with high quality transmission line stringing machines and solutions to safely execute their stringing projects, while maximizing their working efficiency.
We offer a broad range of stringing machines and tools for power transmission lines, including anti-twisting braided steel wire ropes, stringing blocks, self-gripping clamps, engine powered winches, working platforms, braided ropes, hydraulic crimping tools, digital dynamometers and much more stringing equipment and control instruments.
-
Anti-twisting Galvanized Steel Wire Rope
This anti-twisting braided steel wire rope is extensively used as pilot wire rope or pulling rope in the construction of overhead transmission lines, and suitable for laying underground transmission cables.
-
Aerial Roller
These stringing blocks are provided with single sheave, three sheaves and five sheaves, which are used for single conductor, two or three bundled conductor, and four or five bundled conductor.
-
Self-gripping Clamp (Aluminum Alloy)
The self-gripping clamps are an aluminum alloy automatic clamp used to anchor and string conductors and steel ropes. Additionally, these self-gripping clamps are also suited to adjust sag in the operation of erecting wire.
-
Automatic Come Along Clamp (Steel)
The automatic come along clamps are primarily used to hold conductors and ground wires in the operations of overhead transmission line construction. They are also used to adjust the sag of conductor.
-
Engine Powered Winch
These gasoline or diesel engine powered winches are widely used in operations of tower erection, wire tightening, cable hauling and underground laying of cables.
-
Working Platform
Our working platforms are made of high grade aluminum-magnesium alloy materials that are characterized by lightweight and high strength. These aluminum alloy working platforms allow operators to access to overhead line work areas.
-
Platina Rope (Dyneema Braided Rope)
Dyneema braided ropes are extensively used as pulling ropes for overhead transmission line construction and rescue ropes for rail cars. 12-strand braided rope with PES sheath is generally used in the construction of transmission lines thanks to its anti-rotation property.
-
Hydraulic Compressor (Crimping)
This hydraulic compressor is a hydraulic crimping tool consisting of hydraulic presshead and hydraulic pump unit. The hydraulic compression machine is primarily used for connection of two ends of aluminum or steel conductor and earth wire.
-
Digital Dynamometer
The digital dynamometer is an electronic force measurement device used to measure the gravity or pull force, featuring high durability and light weight. Fabricated with high grade alloy steel and powered by four "AA" batteries, this digital dynamometer is suitable for wide-range force measuring.
-
6481 Series Optical Fiber Fusion Splicer
6481 series optical fiber fusion splicer is commonly used for the connection and protection of all kinds of optical fiber, such as communication optical fiber cable and erbium-doped optical fiber.
-
6420A/6422 Optical Time-Domain Reflectometer (OTDR)
The 6420A and 6422 OTDR with 7-inch display screens are designed for testing PON FTTX, MAN, and long-distance optical fiber networks. Various modules are available, including SM 1310nm, 1490nm...
-
BOU350 Series Optical Laser Source
Laser Source is part of the toolbox essentials working in pair with optical power meters to measure the optical attenuation and eliminate the faults when telecom technicians install or maintain optical fiber networks.
-
