Product Overview

Our company's independently developed AMHWX-12 outdoor high-voltage ring network box (open lock) has passed the type test of the National Electrical Product Quality Supervision and Inspection Center. The product is widely used in 10kV/6kV distribution systems and is a switch product for various urban and rural user distribution systems.

The switchgear adopts a modular unit mode, which can be combined according to different purposes. It is divided into two categories: fixed unit combination and expandable unit combination, meeting the flexible use needs of various substations for compact switchgear.

The AMHWX-12 outdoor high-voltage ring network box (open lock) is a fully sealed system, with its charged components and switches enclosed in a stainless steel body. The entire switching device is not affected by external environmental conditions, thus ensuring operational reliability and personal safety. And maintenance free has been achieved. By selecting expandable busbars, any combination can be achieved, achieving full modularity. The expansion of busbar safety insulation and shielding ensures reliability and safety. The AMHWX-12 outdoor high-voltage ring network box (open and close) can also provide TV-based automation solutions, forming the concept of intelligent switches and reducing on-site installation and debugging workload.

The AMHWX-12 outdoor high-voltage ring network box (open lock) is divided into non expandable standard configuration and expandable standard configuration. Due to the combination of full module and half module, as well as self scalability, it has extremely special flexibility.

AMHWX-12 outdoor high-voltage ring network box (opening and locking) shall comply with GB standards. The design life for operation under indoor conditions (20 ℃) exceeds 30 years.

Model and meaning

Functions and Features

The AMHWX-12 outdoor high-voltage ring network box (open and close) uses SF6 gas as the arc extinguishing and insulation medium.

The switchgear is a fully sealed and insulated structure; the busbar, switch, and live parts are completely enclosed in a stainless steel shell. The chamber is filled with 1.4bar SF6 gas, with a protection level of IP67: the entire switching device is completely unaffected by external environmental conditions, and can ensure normal operation of the switch even in extreme situations such as short-term water immersion. The product is maintenance free for life.

The switchgear has a complete "five prevention" interlocking device, completely eliminating the possibility of personnel and equipment operation failures caused by human error.

All switchgear cabinets have reliable safety pressure relief channels, which can ensure the personal safety of operators even in extreme situations.

The switchgear is divided into two types: fixed unit combination and expandable unit combination.

The switchgear usually has front inlet and outlet lines, and can also be installed in different positions to achieve side outlet or side expansion.

The cabinet size is easy to install and can be suitable for places with limited space and poor environmental conditions. The switchgear can be equipped with electric, remote control, and monitoring devices according to different user needs.
