Summary:

35KV prepaid dry metering box quotation This product is suitable for 50Hz AC, rated voltage 35KV three-phase line supply voltage, current for energy metering.

3. Main technical parameters:

3.1. The product is made of special outdoor materials, which can adapt to outdoor wind, sand, rain, fog, dew and purple.

The natural environment such as external line and temperature difference (-45 ~65 ~C) can avoid oil leakage and oil deterioration of oil-immersed products.

The shortcomings of flammability and explosiveness can be realized without oiling, which saves the trouble of preventive test of oil-immersed products every year.

A lot of manpower and material resources.

3.2. Voltage transformer of this product strengthens the end insulation and interlayer insulation of primary coil and installs capacitive screen device, which has resistance

Lightning impulse, operation overvoltage, resonance overvoltage, high frequency overvoltage, low frequency overvoltage and other performance.

3.3. Both high and low levels are sealed to enhance the anti-theft effect.

3.4. Change in sculpture, clear and clear, not easy to wear, never fade, easy to check and so on.

Point to avoid stealing electricity by changing the sign and changing the ratio of the sign. Quotation of 35KV Prepaid Dry Metering Box

3.5. Voltage cores are made of imported high-quality cold-rolled oriented silicon steel sheets. Current cores are made of high-quality oriented silicon steel sheets or joints.

Gold production.
