Description

Wind can drive a tubular busbar into resonance and damage the installation. The SDAM damper is fitted on the tube and dissipates vibration tuned to the tube's natural frequency, replacing the usual cable inside the tube. The group also includes an adjustable elbow connector joining aluminium tubes at 60–180° without bending or welding; the angle is set without disassembly.

Features: Bodies are cast from primary aluminium alloy EN AC-42100 T6, copper parts from EN 1982 alloys; hardware is A2-70 stainless steel (DIN 933, EN ISO 3506-1) with PTFE-based anti-seize coated nuts. The design rule is that at full load the connector runs cooler than the conductor. Design and type testing follow ANSI/NEMA CC1, IEC and BS EN.

Specifications: SDAM damper — damping of wind-induced tube vibration; Adjustable connector — 60–180° angle, sand-cast EN AC-42100 T6 body, gravity-cast caps, 5 A2 bolts (A4 on request), different tube diameters.

Applications: outdoor substations 110–750 kV, aluminium tube and conductor busbars, connection of equipment.

Selection by conductor and tube diameters, design and quantity is made from an inquiry form; delivery time and terms are confirmed by our manager.
