Station transformer for heating concrete SPB-40 In connection with the widespread intensive construction of private, residential multi-apartment and industrial buildings and other reinforced concrete structures, there is an urgent need to warm up concrete in winter and accelerate the processes of hardening of structures. An irreplaceable assistant in this matter will be a transformer station for heating concrete SPB-40. Basically, this device is used not only in the cold season, but is also used to accelerate the pace of construction in the range of ambient temperatures from +10 to -40C. The average power of this device allows it to be used both in the private sector and in the course of mass construction. The device is distinguished by its simplicity and reliability of design, ease and convenience of switching heating modes. The presence of slinging eye-clamps on the body allows increasing the mobility of the station within the construction site and simplifies its transportation and handling. The SPB-40 concrete heating transformer station is equipped with control devices for the supplied current. The SPB-40 concrete heating station is manufactured with a dry-type transformer in two versions: with aluminum and copper windings. Natural air cooling and the presence of a circuit breaker in the design make the device extremely safe even in the most difficult operating conditions.
