SOHO's preformed armour rod The main function of the armour rods is to protect conductors/strands against bending, compression, abrasion and arcover damage and to provide restorative repair. They are usually installed in the suspension points for suspension clamp & AGS clamp.

The rods of fittings are refaced in the ends to avoid damages in the assembly and to the specified conductor. Refacing of the ends is made by abrasion in the rods up to 4,6 mm. When these rods are of aluminium and the diameter is major or equal to 5,18 mm, are BALL-ENDED rods.These rods can be made with PARROT BILL ENDED rods to meet the corona onset and RIV requirement for most extra-high voltage application.

SOHO stockbridge damper respond to wind induced line vibration that is characterized by high frequency, low amplitude motion also know as aeolian vibration. SOHO stockbridge damper with Large and Small weights can achieve greater power dissipation and frequency response performance than “symmetrical weight” Stockbridge damper designs.  Wider frequency coverage translates into better protection as energy is more effectively dissipated over the entire range of conductor/cable frequencies.

SOHO standardized internationally according to the following standards:

● IEC 61897 Overhead lines - Requirements and tests for aeolian vibration dampers

SOHO Spacer & Spacer Dampers for Twin-conductor, Triple-conductor, Quadded-condcutor and Hex Bundles conductor feature elastomer damping elements engineered to absorb maximum energy.  This design provides the greatest possible resistance to conductor fatigue by eliminating the need for additional vibration dampers.

SOHO standardized internationally according to the following standards:

● IEC 61854 Overhead lines - Requirements and tests for spacers

SOHO's Arcing Horn is basically projected conductors used to protect the Insulators in High Voltage Transmission Line from damage during flashover. Over voltage on Transmission Line may occur due to various reasons like lightning strike, sudden load variation, fault etc. Due to this high voltage a flash over may take place which will shatter the Insulator. To prevent Insulator from such an occurrence, it is very important that flashover do not take place through the Insulator. Arcing Horn serves this purpose by providing a bypass flashover the high voltage across the insulator using air as a conductive medium.

Application:66kV to 220kV

Counterweight or Jumper weight are available for single, twin, triple and quad conductor configurations. unitl weights range from 5kg to 50kg.

Combined 85kg(or according to requirement) clamp weights are available for  twin, triple and quad conductor bundles. These overhead clamp weights are supplied complete with aluminum liners where applicable. 

All weights are galvanized in accordance with ISO 1461.

All kinds of Danger plate and Serial numbers plate.

● Plate material:Aluminum or steel

● Surface:Reflective or without reflective

● Content: Customization

● Color: Customization

● Dimension: Customization

● Number plate: Different number for each plate can be customized

SOHO's arcing horns are not to be confused with SOHO's corona rings (or the similar SOHO's grading rings) which are ring-shaped assemblies surrounding connectors, or other irregular hardware pieces on high potential equipment. Corona rings and grading rings are intended to equalize and redistribute accumulated potential away from components that might be subject to local accumulation and destructive discharges, although sometimes either device may be installed in close proximity to an arcing horn assembly.

Application:330kV to 500kV
