The Vertical Busbar Support is a critical component in electrical switchgear systems, specifically designed to provide robust and reliable support for vertical busbars. Constructed from high-strength, insulating materials such as fiberglass-reinforced polyester or epoxy, these supports ensure optimal electrical insulation and mechanical stability. They are engineered to withstand high mechanical stress and thermal expansion, maintaining the busbars' alignment and preventing sagging or misalignment that could lead to electrical faults.

Vertical Bus Switchgear Assembly The vertical busbar bracket is an important component in the switchgear assembly. It is made of epoxy resin, a common insulating material, which has excellent electrical insulation properties, durability and resistance to moisture and temperature changes. The vertical busbar bracket produced by Reziger can be flexibly configured according to different power requirements and application scenarios to meet the individual needs of users. The function is to fix the vertical busbar (a conductive metal rod carrying current) in the switchgear chassis to ensure that the busbar is correctly aligned and insulated from the surrounding environment to ensure that the current will not be damaged or overheated.

Electrical Cabinet Self-locking Device (Electrical Cabinet self-locking Device) is a kind of safety protection equipment for electrical control cabinets and electrical equipment, and its main role is to automatically realize the locking and unlocking of the cabinet door. The device is usually combined with the power control system of the electrical equipment or the switch of the operation panel, and adopts the principle of mechanization to ensure the safety and stability of the cabinet. In this way, the security of the equipment can be effectively enhanced to prevent unauthorized operation, equipment damage or misuse, so as to ensure the normal operation of the electrical equipment.

SOLH MAL lightweight aluminum alloy mini pneumatic cylinders are ultra-economical compact actuators designed for light-duty automated applications. Constructed with hard-anodized aluminum barrel and end caps paired with anti-rust stainless steel piston rod, this model is 15% lighter and around 10mm shorter in overall length compared with conventional MA series cylinders while greatly cutting procurement costs. It features excellent dimensional interchangeability with MA and CM2 cylinders for straightforward replacement and low-cost equipment retrofits. Adopting dual-end thread locking assembly ensures stable structural performance during continuous operation; the streamlined round body allows easy disassembly, inspection and maintenance. A full portfolio of variants covers standard double-acting, spring single-acting power-off reset types, synchronous double-rod units and stroke-adjustable MALJ versions to meet diverse light-load linear motion requirements. Standard rubber bumpers absorb mild shock and noise, with optional adjustable air cushions available for high-speed frequent cycling. Low-friction composite sealing with built-in oil storage grooves supports oil-free maintenance-free operation with a service life reaching 5 million cycles. An optional built-in magnetic ring works seamlessly with SMC M9B and Airtac CS1-G magnetic sensors to achieve real-time piston position feedback and PLC automatic linkage control. Supported by stable mass production and fast order fulfillment, these budget-friendly cylinders are widely applied in electronics assembly, packaging machinery and light industrial automation under dry and low-dust working environments.

SOLH HRQ dual piston rack & pinion rotary cylinder includes micro sizes HRQ2/3/7 and medium-to-large HRQ10~HRQ200 with infinitely adjustable swing angle 0~190°. It outputs higher torque and stronger bending/radial load capacity than vane rotary actuators. Three configurations are available: basic mechanical stop buffer (low-cost for light low-speed duty), -A integrated hydraulic shock absorber (high-speed heavy load precise stopping), and -A(S) hydraulic version with stainless steel end caps for humid & slightly corrosive environments. The rotary table features central hollow through hole for tubing and wiring, and side sensor slots compatible with universal magnetic reed switches. Micro models adopt bottom mounting holes while medium/large sizes provide multi-side mounting taps for flexible layout. Pre-filled long-life grease enables lubrication-free operation. Selection requires simultaneous verification of torque, radial/axial load and bending moment. Widely used for rotary indexing in automatic assembly, material sorting, packaging capping and jig turnover stations.
