Automatic circuit breaker tester UPA-3 is designed for testing and ampere-second characterization of automatic AC current circuit breakers. The device allows registering the value of the supplied current and timing the automatic circuit breaker switching interval. Circuit breaker tester UPA-3 is a mobile device, which could be easily transported to a required testing location. Circuit breaker tester UPA-3 operates on the principle of varying the power in the primary circuit of the matching power transformer and, respectively, varying the output current, flowing through the automatic circuit breaker under the test. Power regulation could be done either through an external regulator (RNO or VR) or through a built-in thyristor controller.
We produce piston, plunger and telescopic hydraulic cylinders with a piston diameter from 32 to 300 mm, with a rod diameter from 10 mm to 250 mm and with a stroke up to 8000 mm, with any kind of mountings and attachments. Our cylinders are available in many versions. Type: - single/double acting - plunger - single/double acting telescopic cylinders - welded - screwed (ISO) - low pressure to max. 350 bar - end/position damping - valve tehnology - integrated sensors
The electro-hydraulic thruster is employed as a driving gear for spring-applied drum brakes of lifting equipment as well as other machinery serving for mechanization of various production processes.
It is a mobile hydraulic device. Mobile ramp is installed in warehouses and cargo docks for loading/unloading semi-trailers, road trains, containers, wagons. Transported by forklift. Safety margin +30%
The drum brakes are applied for stopping and holding shafts of mechanisms in a braked position as the driving gear is off.
Uses of base oil sn500 Base oil sn500 use in manufacturing of many lubricants oil , who produce base oil mostly use sn500 as additive in their other product also blenders and compounders are other user of base oil different grades as well as sn500 , mostly base oil add from 1% up to 20% as additive to other products . base oil use in different oil as well is engine oil , motor oil , hydraulic oil , gear oil etc.
