2. Routine mechanical test

MARKING AND LABELLING
Manufacturer's Name or Trademark;
ii) Manufacturer's Type Designation;
iii) Specified Electrical Characteristics;
iv) Specified Mechanical Load.

MARKING
Each insulator unit is marked with the name or trade mark of the manufacturer and the year of manufacture in accordance with IEC 61952 and means to ensure a system of trace-ability for each of the component parts. In addition, each insulator unit is marked with the specified mechanical failing load in conformity with lEC 61952 and client' requirements.

Insulator units shall be packed in plywood cases or solid wood cases. The packing shall afford adequate protection for the insulators during handling and shipping. We can provide CO(Original Certificates) if client need.
