OMB-17.5 (JLSZXW3-17.5)
Overhead Pole Mounted Primary Metering Unit
This type of metering box is an outdoor dry-type three-phase primary metering unit. The medium-voltage metering transformer is assembled by 3 single-phase combined transformers. Each single-phase combined transformer contains 1 set of CT coil and 1 set of VT coil, Cyclic epoxy resin (CEP) vacuum casting solid encapsulation, with excellent insulation performance and hydrophobicity, the surface is resistant to acid and alkali corrosion, contamination, and UV. It is suitable for outdoor overhead line installation and connection to public power systems. The metering box has connected the secondary lead of the transformer to the junction box of the centralized terminal. The sealing design of the junction box has an output port to connect with the meter box, which is quick to install. It is suitable for the equipment in the urban and rural power distribution network with the maximal voltage not more than 17.5kV for electric energy metering, current and voltage measurement.
