What is the Insulator Rod?
Composite insulation rod, also called pultrusion electrical insulation rod. It plays the dual function of mechanical connection and internal insulation in the composite insulator structure. Composite insulators are Divided into suspension and post according to their application. These two structures have different requirements for the mechanical state of the composite insulators. Suspension is mainly concerned with tensile strength and post is mainly concerned with bending strength and torsional strength. According to the rich experience accumulated over 20 years, Taporel believes: how to choose a suitable composite rod can refer to the following factors: Determining the length of the rod and using the E-glass rod or ECR glass rod by the voltage requirements and operating environment of the insulator. The mechanical requirements of the insulator are used to determine the diameter of the rod and the requirements for the vulcanization temperature during the manufacture of the insulator are used to determine the temperature class of the rod to be selected. We will communicate with customers and give the best choice of technical solutions in the fields of glass fiber materials, rubber compounding, and process design. Provide customers with the most reasonable price-performance products.

Standards
We refer to the following criteria, but some indicators are higher than the following standards:
National standard: GB/T19519
Power industry-standard: DL/T1580 DL/T810 DL/T864
International Electrotechnical Commission Standard: IEC61109 IEC61952
American Standard: ANSI C29.13
Why choose the composite insulator core rod without mold release agent?
No mold release agent vacuum pressure injection epoxy glass fiber pultrusion rod is based on synthetic resin, glass fiber (alkali-free glass fiber yarn) is the reinforcing material, its production is the glass fiber yarn impregnated with an epoxy resin matrix, through the continuous pultrusion (or extraction) process made into a certain diameter of composite insulator rod. This product has the following advantages: lightweight, stable mechanical properties, excellent insulation performance, covering 10kV-1000kV voltage range. The tensile properties of the product are particularly outstanding, and its tensile strength reaches 1360Mpa or more.
