Industrias Aplicables

El grifo de cable a prueba de explosiones is a critical sealing device installed at the entry point of explosion-proof equipment enclosures. Through its precision clamping and multi-seal design, it ensures that the introduction of cables does not create any weak points or leaks that could compromise the equipment’s explosion-protection rating or ingress protection (IP) rating. These grilletes certificados are used extensively across industries such as petroleum and chemicals, natural gas, coal mining, metallurgy, military, nuclear power, shipbuilding, ports, and railways.

Credibilidad

Our grapas de cable a prueba de explosiones certificadas hold certificates of conformity issued by authorized bodies, including ATEX, IECEx, and EAC. These certifications ensure the explosion-protection marking, ingress protection rating, and other key parameters are fully compatible with specific application environments.

FAQ (Frequently Asked Questions)

• Q1: What is a “Dual-Certified” cable gland?
  • A1: It refers to a product that holds two different explosion-protection certification systems (e.g., ATEX & IECEx) to ensure the highest standard of regulatory compliance.
• Q2: How to quickly verify an installed gland?
  • A2: Check for cracks, corrosion, or modifications; confirm specifications match the equipment; and ensure all locking nuts are securely tightened.
• Q3: When is an explosion-proof plug required?
  • A3: For sealing unused ports on an enclosure to maintain certification integrity, or when cables are temporarily removed for maintenance.
• Q4: Why is a matching gland critical?
  • A4: Una glándula no conforme única puede convertirse en el eslabón más débil, creando una ruta de fuga fatal que anula la protección de todo el valioso activo.
