Product Overview
SafeSwitch is an air insulated (AIS), metal enclosed, switchgear cubicle. It is suitable for electric distribution automation and compact, expandable metal enclosed switchgear. It features a simple structure, flexible operation, reliable interlocking, and convenient installation, which provides satisfactory technical solutions for different application scenarios and users.
With the adoption of modern sensor technology, up-to-date protection relays, advanced design, and flexible assembly projects, SafeSwitch completely meets the requirements of a continuously varying market.
SafeSwitch can be equipped with an SF6 load break switch. According to user demands, it can also be assembled with a vacuum circuit breaker. Operational methods can be manual or motor-driven.
Key Features & Layout
1
Load Switch
Load switch and earthing switch housed in an enclosure filled with SF6, satisfying "sealed pressure system" requirements.
2
Busbars
All busbars are positioned in the same horizontal plane, enabling convenient switchboard extensions and connection to existing equipment later on.
3
Connection
Accessible through the front, connecting to the lower load switch and earthing switch terminals, or the lower fuse-holders. This compartment is also equipped with an earthing switch downstream from the MV fuses for protection units.
4
Operating Mechanism
Contains the elements used to operate the load switch and earthing switch, and activates the corresponding positive break indications.
5
Low Voltage
Allows installation of a terminal block (if the motor option is selected), LV fuses, and compact relay devices.
* If more space is required, an additional enclosure may be added on top of the cubicle.

Why Choose Us
Limit Innovation
In the traditional electrical equipment business, where technologies like cast resin, vacuum arcs, and digital protection have been used for decades, we implement a "limit innovation" policy on our mature products:
- Update products only when latest official standards are revised.
- Produce new products only when related technologies are fully mature.
- Focus limit innovation on external updates to improve ease of use and transport.
Our Mission & Vision
Recognizing that power infrastructure in many developing regions still requires improvement, our mission is to provide highly cost-effective products compliant with international standards (IEC and IEEE). These solutions are adapted from widely used, proven, and reliable products developed over the past thirty years.
Ultimately, we aim to help developing regions upgrade their energy quality and improve lives.

Frequently Asked Questions (FAQ)
What IEC standards does this Air Insulated Switchgear comply with?
This switchgear complies with several key standards, including IEC 62271-100 (circuit breakers), IEC 62271-105 (switch-fuse combination), IEC 62271-102 (disconnectors/earthing switches), IEC 62271-200 (metal enclosed switchgear), IEC 60694, IEC 60265-1, and IEC 60529 (IP code ratings).
What are the environmental limits for installing this switchgear?
It operates reliably in temperatures ranging from -25℃ to +40℃, with daily average humidity up to 90% (monthly average 95%). The maximum installation altitude is 2500m above sea level, and it requires ambient air free from corrosive or flammable gas.
What types of switches can be integrated into the SafeSwitch?
SafeSwitch can be equipped with an SF6 load break switch. Depending on customer requirements, it can also be configured and assembled with a vacuum circuit breaker.
Can this equipment be operated remotely or automatically?
Yes, operational methods for the switchgear can be set up for either manual configuration or motor-driven operation to fit automation and control requirements.
How does the modular design allow for future switchboard extension?
The busbars are arranged strictly on the same horizontal plane. This design characteristic allows for convenient later extensions of the switchboard and easy connection to existing MV equipment.
What strict guidelines govern the transport and delivery of your electrical products?
All products are specifically designed with a "fit to container" rule to ensure they can be safely loaded and shipped. They are also pre-tested in the factory and delivered with comprehensive, readable drawings and manuals.
