1.Introduction of OPGW cable
OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. It’s working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.

The OPGW consist of stainless steel tube optical unit, aluminium cladding steel wire, aluminum alloy wire.It has central stainless steel tube structure and layer stranding structure. We can design the structure according to different environment condition and customer’s requirements.

OPGW cable

Features:
• Stainless-steel optical fiber unit of central loose tube or layer stranding structure
• Aluminium alloy wire and aluminium clad steel wire armored
• Coated with anticorrosive grease between layers
• OPGW can support heavy load and long span installation
• OPGW can meet the ground wire‘s requirement of mechanical and electric by adjusting proportion of steel and aluminium.
• Easy to produce the similar specification of exist ground wire can replace the exist ground wire.

PVC Bird Diverter

PVC Bird Diverter is designed for use on overhead conductors to create greater visibility for avian flight paths on overhead lines and tower down guys. Offering little wind resistance, it reduces hazards to both lines and birds. For low and medium voltage construction, apply flight diverter to phase conductors (bare or jacketed). For high voltages, it is typically used on shield wire.

Flight diverter is lightweight, offers little wind resistance and is easily and quickly applied by hand or hot stick. The positive grip on the conductor isdesigned to ensure that flight diverter remains in the applied location and does not move along the span under Aeolian vibration or other conditions.

PVC Bird Diverter

Materials:
Manufactured from rigid high impact polyvinyl chloride (PVC), Fly diverter possesses excellent chemical resistance, strength properties and will retain good physical characteristics within a range of extreme temperatures. Industrial fumes and salt water cannot seriously degrade the properties of rigid PVC.

Features:
1.Flight diverters are designed to offer the following advantages:
2.Increased conductor profile to provide increased visibility where large, slow moving bird flight paths are present
3.Economical and easily applied
4.Lightweight
5.Long service life without deterioration of material properties
6.Minimal wind resistance

Preformed guy-grip dead ends

Preformed guy-grip dead ends are used for fixing terminals tower stay wire and where the large size stay wires are needed, such as electric transmission line, antenna, correspondence and lines etc, which can replace the common U-T clamps and wedge type clamps of line tower. The  clamp structure is simple. Two legs of Helical wire form an empty pipe, and its rear is a Helical stranding link. After coiled around the stay wire, the two legs of Helical wire can generate great grip strength, and stranding link is fixed on the earth anchor or tower. The unique theory and structure provide the clamp with particular function and vivid characters.

guy-grip dead ends

1.Component: Inner preformed wire, outer preformed wire, suspension link, ground wire.
2.Usage: OPGW preformed rods tension clamp is used for OPGW cable route’s fixing and anchor shackling. Usually be installed on the terminal tower, tight tension tower and intersection angle tower etc.

Feature:
1.The holding strength can reach over 95% RTS without the effects of stress concentration and vibration stress.
2.Excellent aluminum clad steel improve the mechanical and resist-corrosion function, extend life.

Preformed ADSS & OPGW cable tension set

Preformed ADSS & OPGW cable tension set is designed to connect ADSS/OPGW cables and tensile poles(or towers). Aluminium clad steel rods can protect and provide cushioning to the ADSS/OPGW cables. The special design of helical rods makes ensure that tension sets can not cause undue stress to the ADSS/OPGW cables
so that the normal lifetime of cable system is ensured.Aluminum clad preformed strand can protect cable and improve anti-vibration function.With special design, preformed strand can ensure the tension clamp wouldn’t generate stress concentration which big enough to damage OPGW cable.The consumers can choose tension clamp according to cable diameter, maximum allowable tension and spacing.

tension set

Advantage:
1.Stress can be distributed equally among the ADSS/OPGW cable surface without stress centralization to protect ADSS/OPGW cable.
2.It has higher grip strength for the cable and can support higher tensile force when stress doesn't exceed the optical cable's side strength.
3.The grip strength for the cable is not less than 95% rated tension strength(RTS),of the optical cable,fully suitable for the installation of ADSS/OPGW cable.
4.The surface and the smooth shaped of end improve the discharging voltage and reduce the loss of electric power.
5.The superior aluminum alloy material has higher comprehensive mechanical performence and cauterization resisting capability,and extends the lifetime usage.
6.Easy installation, no need for special tools, no need for maintenance.
