Switchgear Door Stopper – Product Details and Applications Product Details: The switchgear door stopper is a critical accessory designed to secure, control, and maintain the proper opening or closing of switchgear cabinet doors. Made from durable materials such as stainless steel, aluminum, or high-grade plastic, these stoppers ensure long-term resistance to corrosion, mechanical stress, and environmental wear. Many models come with adjustable arms or rubber-padded ends to absorb impact and prevent damage during sudden door movements. Switchgear door stoppers can be spring-loaded or magnetically operated, ensuring smooth and stable operation. Additionally, some variants integrate anti-vibration features to prevent door movement due to mechanical operations, such as relay switching or breaker tripping. Their compact design allows for easy installation, either by screwing or clipping onto the door frame or cabinet base.

SOLH C85/CD85 stainless steel mini cylinder complies with ISO 6432 international standard and can be directly interchanged with equivalent SMC models. Bore sizes: φ8/10/12/16/20/25 mm. Barrel and piston rod are made of 304 stainless steel with excellent rust and corrosion resistance, applicable to humid, mild acid & alkali environments, as well as clean production lines for food, pharmaceutical and electronics industries. Adopting tie-rod-free crimped end cap structure, the cylinder features slim and lightweight design. Complete variants include standard double acting, single acting spring return/extend, double rod synchronous type and C85K square non-rotating rod cylinder. CD85 versions are equipped with built-in magnetic ring for position detection via magnetic switches. Standard rubber cushion is supplied; suffix C air cushion is optional for φ10~25 models to absorb impact under high-speed operation. The minimum starting pressure reaches 0.05MPa, supporting long-term oil-free operation with piston speed from 50 to 1500 mm/s, perfect for high-frequency short-stroke reciprocation. Full sets of ISO standard mounting options are available: integrated clevis, flange, foot mount, trunnion mount and more. Compared with MI and MA cylinders, C85 owns globally recognized ISO dimensions, bringing outstanding convenience for equipment replacement in overseas markets. A minimum 50% thrust safety margin is recommended during selection.

Auxiliary Contact Switch The Auxiliary Contact Switch is a switch used in electrical equipment to extend the signal transmission function, assisting in the condition detection of main circuit equipment and providing additional switching signals during signal transmission. It acts as an auxiliary device to the main switch, providing additional contact signals to meet complex electrical control and indication requirements. Used to feedback, control, protect or indicate the status of a system, especially in automation and monitoring systems, plays a vital role. The auxiliary switch consists of a set of normally open (NO) and normally closed (NC) contacts that are synchronized with the state of the main switchgear. When the main device is operating, the contact of the auxiliary switch will be opened or closed according to the operating state of the device, thereby transmitting the signal to the control system or indicating device.

The indoor high-voltage AC ground switch is a critical safety component in high-voltage systems, designed to disconnect and ground electrical equipment during maintenance, ensuring operator and equipment safety. Suitable for voltage levels from 12kV to 40.5kV, it offers robust short-circuit resistance and stable mechanical performance. Its streamlined design allows for easy installation and smooth operation, making it well-suited for use in high-voltage switchgear and electrical substations. Engineered to meet international safety and performance standards, this grounding switch delivers reliable protection in various power system applications.

Switchgear Door Lock Bent Plate – Product Details and Applications The Switchgear Door Lock Bent Plate is a critical mechanical component designed to enhance the safety and operational integrity of electrical switchgear systems. It serves as a key element in the door locking mechanism, ensuring the secure closure of switchgear cabinet doors. Typically made from robust materials such as stainless steel or zinc-coated metal, the bent plate offers durability, resistance to corrosion, and strength under mechanical stress, ideal for both indoor and outdoor switchgear installations. The bent plate features precise bends and dimensions to fit perfectly within the locking assembly, working seamlessly with handles, latches, or electromagnetic locks. It plays a crucial role in achieving smooth mechanical alignment between the door and frame, preventing accidental door openings caused by external vibrations or impact. Some variants are designed to support additional locking mechanisms, such as padlocks, to offer enhanced access control and security during maintenance or operation.
