What Is the Breaking Strength of Cable Seals?

The breaking strength of Cable Seals refers to the amount of force required to break the steel cable once the seal is locked. This strength varies depending on the cable diameter, material quality, and seal design.

In general, cable seals offer breaking strengths ranging from 300 kg to over 2,000 kg:

• 1.5 mm cable seals: approx. 300–500 kg

• 2.0 mm cable seals: approx. 500–800 kg

• 3.0 mm cable seals: approx. 1,000–1,200 kg

• 5.0 mm cable seals: approx. 1,800–2,000+ kg

High-strength cable seals are commonly used for shipping containers, trucks, rail transport, and high-value cargo, where increased resistance to cutting or pulling is required. Many cable seals are tested according to ISO 17712 standards, ensuring consistent performance and reliability.

Choosing the correct breaking strength depends on the security level required, regulatory compliance, and the application environment.
