Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of insulation isolation columns, it is recommended to prioritize checking parameters such as voltage rating and material dielectric constant to ensure compatibility with the equipment working environment. For example, there may be differences in insulation performance requirements between high-voltage distribution cabinets and photovoltaic inverters.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable supply capabilities in the field of electronic components or power equipment.
  • Insulated isolation columns are commonly used in PCB board fixation or bus duct support scenarios. When purchasing, the structural specifications should be selected based on the installation method (thread/buckle) and load-bearing capacity to avoid displacement risks caused by insufficient mechanical strength.
  • In the field of industrial automation, the temperature resistance range (-40 ℃ to 120 ℃) and flame retardant properties of insulation isolation columns are key considerations. It is recommended to screen parameters based on specific application scenarios such as machine tool control cabinets or rail transit equipment.
