Pressure connectors

ApplicationPressure connectors are used to control pressure equipment, keeping medium pressure within fixed, defined limits. Manufactured in three type-sizes depending upon pressure range (0.4 MPa - 0.8 MPa - 1.1 MPa). LCA pressure connectors are manufactured as mechanized three-line or single-line dual-break manoeuvre low-voltage ac switches. LCA pressure connector is a variety of a normally closed contactor. Its base, body, movable and stationary jaws are made of glass fibre-reinforced plastic. Copper contacts have silver-cadmium oxide tips. Connector casing is made of polycarbonate. Technical dataRated voltage of insulation 380 V Rated frequency 50 Hz and 60 Hz Rated continuous current 16 A Rated test voltage of insulation 2,5 kV Rated frequency of operation 360 cycles/h Mechanical durability 1 * 106 cycles Minimum temperature of driving factor 0oC Maximum temperature of driving factor 40oC Type of driving factor water, air, machine oil, transformer oil Maximum velocity of pressure variations 0,05 MPa/s Minimum velocity of pressure variations 0,001 MPa/s Sections of connecting cables min 1,5 mm2 max 4 mm2 Pressure connectors mass 0,45 kg Working conditionsConnectors should be installed in closed compartments free from dust, gases and explosive or chemically active vapours. Permissible operating altitude should not exceed 2 000 m a.s.l. Maximum ambient temperature is 40oC, maximum daily average 35oC, the lowest temperature is -40oC. The lowest relative humidity can be 50% at 40oC and 90% at 20oC. Connector operating position should be cap upwards. Deflection from the vertical should not exceed 5o. Protection degree IP 430. Connector section Pressure range --------------------------------------------------------------------------------LPAApplication LPA connectors are used for control of pressure equipment with open reservoir, maintaining medium pressure within fixed, defined limits. Manufactured in two type/sizes depending upon switch handle position relative to contacts. LPA connectors are manufactured as mechanized three-line dual-break manoeuvre low-voltage ac switches. LPA float connector is a mechanical variety without return force. LPA pressure connector is a variety of a normally closed contactor. Its base, body, movable and stationary jaws are made of glass fibre-reinforced plastic. Copper contacts have silver-cadmium oxide tips. Connector casing is made of polycarbonate.
