Detailed Description
11 kV - 3150kVA , Cast Resin Dry Type Transformer , Three Phases , Two Winding , Power Distribution
Advantages:
Cast resin dry typetransformer,eco-friendly, high efficiency.
# # Low loss, low noise, low partial discharge, high reliability. Fitfor general users , such as hospital, tower, hotel, etc.
# Strong capability withanti-short circuit, high anti-lightning impulse capability.
# HV coil is vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure. Subject to customer need, both HV and LV coil are fully vacuumed.
# Simulating analysis being used in the core model, the resonance can be avoided and the noise is reduced. Simulation calculation and analysis of lighting impulse wave are applied to the HV Coils; anti-lighting impulse capability is improved.

Cast resin dry type transformer
Care shall be taken to ensure that fittings are located so as not to interfere with the external connection to the bushing terminals, and the clearances to such connections shall not be less than the appropriate minimum phase-to-earth clearance given in column 2 of Table 2. The lines of approach of these connections may lie anywhere within the limits indicated in Figure 1, and the required phase-to- earth clearance shall apply at all points along these lines, as shown at the points marked 'L'. In addition, the minimum vertical working clearances from floor level to live metal shall be as listed in column 3 of Table
Table 2 Electrical clearances in air
