1.Product Description
Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin inssulating bands automatically. The core is made of high-permeable grain-orientated silicon sheet and cast with imported epoxy resin. Thanks to advanced technology, quality raw materials, scientific management, and perfect inspection means, our products have the following features: The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble and has low local discharge, high reliability, and long service life. The high and low-voltage systems are cast under vacuum, thus the coil will not absorb moisture, the clamps of core are subjected to corrosion-resistant treatment and it may run under high temperature or orther serious environments. Flame retardancy, explosion-proof and no environmental contamination. The insulating materials in the coil such as glass fiber are self-extinguishing and they will not generate toxic or harmful gas under high
The standard procedure for making wooden case is as follows:
♦ Receipt of information required for the type of goods to be wood barrel customers.
♦ Measure and create original designs for customers.
♦ Select the type of wood suitable for the requirements of the goods.
♦ Determine the delivery time.
♦ Check the wood barrel technique.
♦ Handover confirmation.
