Product Overview

Summary

HRM16-12/24 fully insulated inflatable cabinet has been obtained from the national high voltage electrical apparatus test center and has been listed as a high-tech product in Zhejiang province. Widely used in 10KVl20KV power distribution system, is the first choice of switches for urban and rural users.

The switch cabinet is modular unit mode, which can be combined according to different uses; it is composed of two types of fixed unit combination and extensible unit, which can meet the needs of flexible use of compact switchgear in various substations.

The HRM16-12/24 fully insulated gas holder is a fully sealed system. All the live parts and switches are enclosed in the bright body of stainless steel. The entire switchgear is not affected by external environmental conditions, thus ensuring operational reliability and personal safety, and achieving maintenance free. By selecting scalable busbar, any combination can be achieved to achieve full modularity. Extended busbar safety insulation and shielding ensures high reliability and safety. The HRM16-12/24 type inflatable switchgear can provide TV automation solutions at the same time. The concept of intelligent switch is formed and the workload of site installation and debugging is reduced to a minimum.

HRM16-12/24 fully insulated inflatable cabinet is divided into non extended standard configuration and extensible standard configuration. Because of the combination of full module and half module and its extensibility, it has very special flexibility.

The HRM16-12/24 fully insulated inflatable cabinet performs the GB standard.

The design life under indoor conditions (40 degrees Celsius) and outdoor conditions (-50 C) is over 30 years.

main features

HRM16-12/24 fully insulated inflatable SF6 gas is used as arc extinguishing and insulating medium.

The switchgear is fully sealed and fully insulated. Busbars, switches and live parts are completely enclosed in stainless steel housing. The cavity is filled with 1.4bar SF6 gas, the protection level is reached, IP67: the whole switch device is completely free from the external environment conditions. Even in the extreme conditions of short water immersion, the switch can also ensure the normal operation of the switch, and the product is free of maintenance for life.

The switchgear has a perfect "five guard" interlocking device, which can completely destroy the personnel and equipment that may be caused by human error operation.

All switchgear have reliable safety relief passageway, even in extreme cases, it can protect operator's personal safety.

Switchgear is divided into two types: fixed unit combination and extendable unit combination.

The switchgear usually comes in and out of the front line, or the side outlet or side expansion can be achieved at different installation positions.

Cabinet size is easy to install, and can be used for narrow space and poor filling conditions.

Switchgear can be equipped with electric, remote control and monitoring devices according to the different needs of users.
