Purchasing Guide

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

  • For procurement requirements that require the use of insulation joints, it is recommended to prioritize confirming key technical parameters such as voltage level, mechanical strength, and weather resistance to ensure compatibility with existing power facilities.
  • In railway or urban rail transit scenarios, insulation joints need to meet stability requirements under high-frequency vibration and temperature difference changes. When purchasing, specifications can be selected based on specific track types.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • Insulation joints made of different materials are suitable for scenarios such as substations or high-voltage transmission lines. When purchasing, the suitability of materials such as epoxy resin or silicone rubber should be evaluated based on corrosion protection requirements.
