PRODUCT SHORT DESCRIPTION
\nFJZ four-split (quad-bundle) spacer damper in cast aluminum alloy for 4-bundle transmission conductors. Suppresses aeolian vibration and sub-span oscillation, corona-free design.<\/p>\n
PRODUCT DESCRIPTION<\/p>\n
The FJZ four-split spacer damper is a key fitting for EHV\/UHV transmission lines that use four conductors per phase (quad bundle). It maintains the prescribed spacing between the four sub-conductors and, through its articulated rubber-damped frame, dissipates wind-induced aeolian vibration and sub-span oscillation while allowing limited conductor movement. The body is cast from high-strength, corrosion-resistant aluminum alloy, with elastomer-damped clamps that grip each sub-conductor without damaging the strands. The open, streamlined frame also minimizes corona and radio interference at high voltage.<\/p>\n
Key Features
\n\u2022 Four-Conductor Control \u2014 Holds four sub-conductors at the design spacing for the whole quad-bundle span.
\n\u2022 Integrated Damping \u2014 Elastomer hinges absorb aeolian vibration and sub-span oscillation energy.
\n\u2022 Articulated Frame \u2014 Allows controlled conductor movement under wind, ice and thermal expansion.
\n\u2022 High-Grade Aluminum Casting \u2014 Heat-treated aluminum alloy offers high strength with light weight.
\n\u2022 Corona-Smooth Design \u2014 Streamlined clamps and rounded edges reduce corona and RIV at EHV\/UHV levels.
\n\u2022 Conductor-Safe Clamps \u2014 Rubber-lined jaws grip strands without looseness or strand damage.
\n\u2022 Easy Installation \u2014 Bolted clamp halves can be fitted from the line with standard hot-stick tools.
\n\u2022 Standards-Based \u2014 Built to GB\/T 2339 \/ IEC 61854 spacer-damper requirements for bundle conductors.<\/p>\n
