Disc Suspension Insulator
Product name: line insulator/ suspension insulator/ disc suspension insulator/ U70BL
Material: Alumina and silica porcelain
Application: Electricity transmission and transformation
Product name: line insulator/ suspension insulator/ disc suspension insulator/ U70BL
Material: Alumina and silica porcelain
Application: Electricity transmission and transformation
Suspension insulator is used as a winding support for overhead line conductors and mainly bears tension.
Every piece of disc suspension insulator is designed for normal voltage rating 11KV (Higher voltage rating 15KV), thus, by connecting two or more insulator string element, a suspension string that is available for whichever voltage level can be formed.
Disc insulator is one of the models that ordered quiet often by our clients. On behalf of our clients` interests, it is our honor to improve our product design to fit various standards and requirements in different power systems.
Advantages
The porcelain surface is covered a layer of hard glaze, and CLD will provide product with color white, brown, gray or as per customer's specifications.
All raw materials are well selected for CLD`s disc suspension porcelain insulator.
Experienced staff who can control the process to keep key process-operating parameters and ensure the quality.
Quality assurance programmes are taken before our products leave the factory.
