YB355-450 series high-voltage explosion-proof three-phase asynchronous motorDetailed product description：

I. Overview
The YB355-450 series high-voltage explosion-proof three-phase asynchronous motor is a closed self fan cooled squirrel cage motor with international advanced level. Adopting advanced design concepts and absorbing advanced technologies in the design of such motors both domestically and internationally. It has the advantages of small size, light weight, high power, high efficiency, large temperature rise margin, good performance, low vibration and play, low noise, excellent explosion-proof performance, high reliability, etc. It can meet various user needs and is easy to use and maintain.

The YB355-450 series high-voltage explosion-proof three-phase asynchronous motor adopts the latest national standards in China and the International Electrotechnical Commission IEC standards, with a power range of 60kW~500kW. The YB355-450 series high-voltage explosion-proof three item asynchronous motor complies with the provisions of GB755 "Rotating Electrical Machinery Rating and Performance", GB3836.1 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", and GB3836.2 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d ", and is made into an explosion-proof motor with explosion-proof marks of ExdI, ExdII AT4, ExdII BT4, ExdII CT4, suitable for Zone 1 with explosive gas environments. Dangerous areas in Zone 2.

Exd I is suitable for explosive gas environments in non mining working faces of coal mines with methane or coal dust.
Exd II AT4 is suitable for explosive gas environments in Class II, Grade A, temperature groups T1, T2, T3, and T4 used in factories.
Exd II BT4 is suitable for explosive gas environments in Class II, Class B, temperature groups T1, T2, T3, and T4 used in factories.
Exd II CT4 is suitable for explosive gas environments in Class II, Class C, temperature groups T1, T2, T3, and T4 used in factories.

The protection level of the motor body casing and junction box is IP54, and it can also be made into IP55. On this basis, there are derived outdoor (W), humid tropical zone (TH), outdoor humid tropical zone (THW), indoor moderate corrosion resistant type (F1), indoor strong corrosion resistant type (F2), outdoor moderate corrosion resistant type (WF1), and outdoor strong corrosion resistant type (WF2). The performance indicators and installation dimensions of the derived three-phase asynchronous motors are the same as those of the basic series.
