Cable reliability testing and identification
Service Introduction
GRGT has profound accumulation in wire and cable testing and identification, providing one-stop testing and identification services for wire and cable:
1. Match the most appropriate product verification standards according to the cable type and usage environment, and formulate a detailed quality verification plan;
2. Based on the results of the reliability test, the cable quality rating is carried out to provide a basis for the user's product selection;
3. Provide professional failure analysis services for cable products that fail on site to clarify the cause of cable failure and help customers improve quality.
Service Scope
High and low voltage wires and cables for rail transit locomotives;
High and low voltage wires and cables for fuel and new energy automotive;
Other wires and cables;
