Question: Hello,I have an optical fiber cable with stainless steel BX jacket which needs to be installed on the explosion-proof CID1 equipment. I am trying to find a way to seal at the enclosure and one of them I am thinking is to remove the SS jacket and install with conduit fitting using Chicco filling but afraid that fiber won't survive while stripping the jacket, I could ask the manufacturer to leave the fiber without any jacket for that specific space but still very fragile and could end up breaking so looking for help here.Does anybody has worked with a similar installation then please can you share how to handle such an installation?Thanks in advance.
Option 1: Remove SS Jacket and Seal with Conduit Fitting Use a sharp razor blade to carefully remove the SS jacket from the fiber cable, leaving the underlying fiber optic cable intact. Utilize a conduit fitting designed for explosion-proof applications, such as a Type 316 stainless steel fitting. Fill the fitting with a suitable sealing compound, such as Chico filling or another approved sealant. Carefully insert the fiber cable into the fitting and tighten the gland nuts to create a secure seal.
Option 2: Use an Armored Fiber Optic Cable Consider using an armored fiber optic cable that already has a protective jacket, eliminating the need to remove the SS jacket. Armored cables typically have a layer of steel or stainless steel mesh that provides protection against impact and abrasion. Install the armored cable directly into the explosion-proof enclosure using a suitable conduit fitting.
Option 3: Consult with Manufacturer As you suggested, contact the fiber optic cable manufacturer and inquire about the possibility of providing a specific length of cable without the SS jacket. Explain the requirement for explosion-proof installation and discuss alternative sealing methods that may be suitable for the fragile nature of the fiber.
Tips for Handling Fragile Fibers Use extreme caution when handling fiber optic cables, especially when stripping jackets or bending them. Bend the fibers in a gentle arc, avoiding sharp angles or excessive force. Utilize fiber optic splice trays to provide support and protect the fibers during installation. Refer to the manufacturer's instructions for specific handling guidelines and recommended sealing methods.
Additional Considerations Ensure that the explosion-proof enclosure meets the necessary certifications and requirements for the hazardous location. Conduct electrical continuity tests on the fiber optic cable before and after installation to verify the integrity of the seal. Regularly inspect the installation for signs of damage or wear and tear, and perform maintenance as needed to maintain the explosion-proof integrity. Flag for review
