3VT Overhead Pole Mounted Metering Unit

17.5KV Pole Mounted Metering Unit

3CT Pole Mounted Metering Transformer

1.Product Introduction
1.1 Product Type Model:
17.5kV MV Overhead Pole Mounted Metal Casing Dry type Metering Box
Product Model:
JLSZXW8-17.5 Combo Transformer

1.2 Product Overview
This type of metering box is an outdoor metal-sealed box encapsulating three-phase primary metering unit with epoxy resin cast dry-type transformer pre-installed inside. The box is made of stainless steel or low carbon steel with protective coating. The surface is resistant to acid and alkali corrosion, pollution, and UV. It is suitable for outdoor overhead line installation and connection to public power systems. The metering box can be equipped with a metering gauge box. All the secondary leads of the transformer can be connected and collected in the meter box. It is also equipped with a testing terminal block and a meter installation space. The meter can be accessed and connected as per user’s requirements and it is suitable for electric energy measurement, current and voltage measurement in urban and rural power distribution network lines with a maximum voltage of 17.5kV and below.

2. Product Function and Use

Overhead pole mounted primary metering unit complies with the latest applicable industrial standards and local and or national electrical code (such as IEC, IEEE (ANSI), CAN, GOST, CEF). It is used for three-phase overhead power grid energy measurement management and distribution network automation management system, the primary side measurement is more accurate, and the power loss of the line can be effectively measured so as to reduce losses.

3. Product Features

1. The whole metering unit is designed with a metal box encapsulated as a whole. Inside the box, there is a dry-type transformer pre-installed and a meter box pre-equipped. It is with high and low voltage integrated anti-theft design, can be installed directly on the pole outdoors, which is convenient and time saving.

2. The metering unit can be equipped with a meter box as required and connected with the transformer interface. The meter installation space is reserved in the box, the alarm signal of the meter box door switch sensor is reserved, and the door lock seal structure is designed to prevent electricity theft.

3. The box is made of corrosion-resistant stainless steel or equivalent performance low-carbon steel with protective coating. The sealing design is weatherproof, acid and alkali corrosion resistant, and UV resistant

4. The medium voltage transformer is insulated with epoxy resin solid encapsulation and has excellent dielectric and mechanical performance. It is oil-free, gas-free and maintenance-free, meeting the requirements of safe operation and environmental protection.

5. The CT of the medium voltage combined transformer can be configured according to double transformation ratios, and the VT is equipped with anti-short circuit and overload protection devices as required to avoid burning and explosion caused by VT short circuit and overload.

6. The primary end is made of silicone rubber composite bushing, and the terminal block of the corresponding area can be configured according to the user's requirements, and the lightning arrester can be optional.
