Descri\u00e7\u00e3o do produto<\/strong><\/h4>\n

The PT handcart is a small car, the extraction part of the central part of the switchgear, and the main electrical components in the switchgear are installed on it, which is what people usually call the handcart. There are generally two types of PT handcarts and switches (circuit breakers). The handcart is also called a small car. Take the switch handcart as an example. In the case of a switch disconnection, the guide rail can be used to pull it out of the switchgear for maintenance or replacement.<\/p>\n
