Global Standards for Medium Voltage Connectors in Mission Critical Facilities

Mission critical facilities, such as data centers, healthcare institutions, and industrial plants, depend on the uninterrupted operation of electrical systems. Medium voltage (MV) connectors play a crucial role in ensuring power reliability and safety. These connectors, which are designed to operate at voltages between 1 KV and 36 KV, must meet stringent global standards to ensure they perform reliably under demanding conditions.

What Are Global Standards for MV shear off screw Connectors?

Global standards are internationally recognized technical specifications that define how MV connectors should be designed, tested, manufactured, and used. They establish minimum performance, safety, and reliability requirements.Common international standards include:

• IEC (International Electrotechnical Commission) standards
• IEEE / ANSI standards in North America
• CENELEC standards in Europe

These standards cover aspects such as:

• Electrical insulation and dielectric performance
• Mechanical strength and retention
• Short-circuit and fault withstand capability
• Temperature rise and thermal aging
• Environmental resistance (humidity, pollution, salt fog, UV)

 Key Global Standards for MV Shear Bolt Connectors

There are several key standards that manufacturers of MV connectors must comply with, depending on the region and specific application.

One of the most important standards for MV connectors is IEC 61238-1, which outlines the requirements for mechanical connectors used in power cables. This standard covers a broad range of testing, including:

• Tensile strength (to ensure the connector can withstand pulling forces during operation)
• Current-carrying capacity (to ensure the connector can handle the required current without overheating)
• Corrosion resistance (important for connectors exposed to outdoor environments)

At Jera Line, mechanical cable connectors and lugs are designed, manufactured, and tested in strict compliance with IEC 61238-1, ensuring long-term electrical, mechanical, and environmental reliability for modern power infrastructure
