Epoxy resin cast dry-type transformers with epoxy glue (potting compound) formulations of the principle of design: the use of epoxy resin WuxiHuiLong pouring 9600GA/9600GB In addition to the dry-type transformer with good mechanical properties, anti-short-circuit capacity, and insulation level high moisture-proof, fire-retardant, self-extinguishing,strong characteristics, but also has a low loss, low noise, small volume Bureau beautiful appearance and so on. Several dry-type transformer insulating materials commonly used to introduce and contrast the performance of dry-type transformer, one of the most critical technology is the choice of insulating materials, and their many varieties, a number of commonly used insulating materials, heat insulation and temperature levels as follows : Grade heat-resistant insulation material dielectric constant name εο volume resistivity (Ω / cm) Inorganic Materials C 3.0-5.0 Glass fiber C 5.0-6.0 A 4.5 General fiber paper |
