Introduction
In low-voltage power distribution systems, safe power cut-off, circuit isolation and load switching are the most basic and critical links. To solve the problems of unclear isolation, misoperation risks and unstable switching in traditional distribution equipment, Zhejiang Xinglihui Electric independently develops and manufactures high-performance Knife switch series and Disconnecting Switch series.
Our knife switch products cover open-type load knife switches, anti-misoperation knife switches and isolating fuse-type knife switches, featuring simple structure, visible breaking points and strong load-bearing capacity. The supporting disconnecting switch series is optimized for equipment maintenance and circuit power-off scenarios, complying with international IEC safety standards. Both series are widely applicable to power grid renovation, mines, oil fields and industrial power distribution cabinets, serving as essential safety switching components for low-voltage power systems.
Core Product Features
Knife switch series: Adopt high-conductivity copper materials, with anti-oxidation and anti-corrosion treatment; equipped with anti-misoperation locking structure to prevent accidental opening and closing; diverse specifications to meet different load current requirements.
Disconnecting Switch series: Realize complete physical isolation of the circuit with obvious visible break points; excellent insulation performance, effectively avoid residual electricity risks during equipment maintenance; durable mechanical structure, frequent switching without deformation.
FAQ – Common Questions from Global Buyers
Q1: What is the main difference between a knife switch and a disconnecting switch?
A: The knife switch is mainly used for load switching and on-off control of conventional circuits, suitable for daily power supply connection and cut-off. The disconnecting switch focuses on circuit physical isolation. It cannot be used for load switching, but provides absolute power-off safety for equipment inspection and maintenance, which is a necessary safety device for power engineering maintenance.
Q2: Are your anti-misoperation knife switches suitable for industrial harsh environments?
A: Yes. All our anti-misoperation knife switches adopt reinforced insulating shells and anti-dust, anti-corrosion structural design. They can stably operate in high-dust, humid and conventional industrial environments such as mines and oil fields, with strong environmental adaptability.
Q3: Do your switches support customized specifications and logo printing?
A: We support non-standard size customization, parameter adjustment and brand logo printing for bulk orders. Our professional R&D and production team can tailor products according to customers’ local power grid standards and engineering project needs.
Q4: What certifications do these two series of products have?
A: All products have passed national safety certification and comply with IEC international electrical standards, which can meet the access requirements of most Southeast Asian, Middle Eastern and African power engineering projects.
