Achieving Optimal Performance

An implosive connector system is a splicing technology that uses implosive energy to join high-voltage conductors instead of hydraulic crimpers. By utilizing the implosive connector system, there is no need to purchase, use, maintain, store, or transport hydraulic crimping tools or dies. The implosive splicing process is easier to work with than the hydraulic crimping process and produces a better-quality connection. 

Material Properties

Extruded aluminum and aluminum alloy tubing are used to manufacture the aluminum components. In contrast, low alloy steel with high fatigue strength and excellent low-temperature performance is used to manufacture the eyebolts and steel sleeves. The eyebolts are forged, and all steel components are hot-dip galvanized.

Conductivity and Corona Performance

The connector's resistance is typically 50% of that of an equivalent conductor length. The Connectors meet the heat-cycling requirements of BS 3288, NEMA CC-3, and CSA-C57. The smooth surface of the connector ensures superior corona performance at all EHV voltage levels.

Corrosion Protection

Compact compression provides corrosion protection, eliminating the need for a filler compound. Implosive connectors play an essential role in maintaining the integrity of transmission power lines; they are part of a broader system of measures designed to prevent corrosion and ensure the reliable operation of overhead lines. 

Quality Standards

Implosive connectors have superior in-place connection quality compared to hydraulic compression fittings. The implosive sleeves remain perfectly straight after implosion jointing, the surface is round and smooth, and the sleeves do not elongate during compression. As a result, no further work is required on the sleeve after compression practice. Furthermore, the phenomenon of "birdcage" is non-existent with implosive connectors.
