Optical Fiber Closure

Optical fiber closure is used for protecting the optical fiber fusion splicing head between two different optical cables; a reserved section of optical fiber will be kept in the closure for maintenance purposes. Optical fiber closure has some excellent performances, such as good sealing property, waterproof, moisture-resistant, and incorrodible after being installed on the electric power line. Optical fiber closure is divided into two types: joint box and Terminal Box, joint box is used for protecting the connection between two optical fiber cables, while Terminal Box is used for a cable terminal or to protect the connection between optical fiber and jumper.

Vibration Damper

Vibration Damper for electric power cable is divided into two types, including spiral vibration damper and 4D vibration damper. It can restrain the Aeolian vibration and wave of the optic fiber cable. Installation quantity, installation site, and installation distance of vibration damper under each span length should be confirmed according to the line circumstance.

Helical Suspension Set

Helical Suspension Set is mainly used for hanging and supporting optical fiber cable on straight pole and tower, to transmit axial load and divert axial pressure which provides good protection for optical cable, to avoid emergencies happen such as too small bending radius or stress concentration. The grip strength of the Suspension Set is larger than the 15% -20% rated tensile strength of the cable, which is fatigue resistance and can serve as vibration reduction.

Helical Tension Set

Helical Tension Set is mainly used in optical cable installation on strain towers, angle towers,s, and dead-end towers. The material of the Helical Tension Set is aluminum-clad steel or galvanized steel wire which has excellent mechanical and electrical performance, to ensure strong electrochemical corrosion and fatigue resistance.

Composite Core Soft Aluminum Stranded Wire

The composite core soft aluminum strand is a composite material whose center is drawn by carbon fiber, glass fiber, and thermosetting resin, and the core member plays a load-bearing role. The effective operating temperature of traditional steel-cored aluminum stranded wire does not exceed 100℃, while the strength is increased by less than 2 times. It sags by 1/2 under high temperature, and the weight per unit length is 10-20% lighter, which avoids galvanic corrosion between different metals.
