Indoor Electrical Cable Tray Construction Standards
IEC 61537 is the internationally recognized benchmark for metal cable tray systems. It applies to cable trays made of steel, stainless steel, aluminum, or other metallic materials. The standard ensures these systems can handle the physical and electrical loads they're exposed to. Cable trays play a vital role in supporting electrical cables and wires in commercial, industrial, and utility installations. For proper installation, design, and maintenance, adherence to international standards is essential.

Communication Optical Cable Foaming Materials
Physical foaming of fiber optic cables is a process used to enhance the properties of cable insulation and improve overall performance. The cable jacket includes an inner surface and an outer surface in which the outer surface is an outermost surface of the optical fiber cable. The portfolio ranges from solutions and equipment for enveloping, sleeving, wrapping & stacking, cast-on-strap to the assembly of automotive, motorcycle, industrial, and e-mobility batteries. Each optical cable is constructed using a precise combination of optical fibers, strength members, buffer tubes. XLPE Foam Material (Cross-linked Polyethylene Foam Material) is a High-Performance (Closed Cell Foam) made of chemically cross-linked polyethylene.
