Model Number: HL-LD68
Brand Name: HOLLEY INTL
Key Specifications/Special Features:
Construction:Meter case: two types of the cases (protective-class I and II) are availableTerminal block: molded of bakelite, voltage test link can be located inside or outside of meter caseDriving element: consists of voltage element and current element, both of which are fixed on steel frame of fine magnetic conductivity, load curve compensation device, load and inductive load adjustment mechanismsRotor: worm is an un-detachable part of rotor shaft so that mesh between worm and shaft improved, both ends of shaft are embedded with graphite bearing to ensure long service life of meterBraking element: magnet is made of AlNiCo5 alloy and designed as U-shaped so that effect of short time over currents upon magnet is negligible
Frame: made of steel, surface is treated by negative electrophoresis to achieve excellent corrosion-proof
Upper bearing: consists of guide pin and brass sleeve, fixed into meter frame by one screw
Lower bearing: both Al-Ni-Co alloy and detachable hard ferrite magnetic bearings are available
Register: adapts heat-/abrasion-proof plastic gears and bearings, no lubrication of bearings is needed during the service life, drum is made of polycarbonate, pyrographed and printed by UV-resistant alumina to ensure non-depigmentation
