**Structure:**
The CU/MGT/XLPE/OS/FR/LSZH/GSWA/LSZH 20x2.5 cable is a high-performance instrumentation cable designed for complex and demanding industrial applications. It features 20 copper (CU) conductors, each with a cross-sectional area of 2.5 mm², ensuring excellent electrical conductivity and reliable signal transmission. Each conductor is insulated with cross-linked polyethylene (XLPE), providing superior thermal resistance, mechanical durability, and long-term performance. A metalized grounded tape (MGT) layer is incorporated to shield against electromagnetic interference (EMI), ensuring signal integrity in noisy environments. The cable also includes an overall screen (OS) for additional protection against external noise. A flame-retardant (FR) layer enhances fire safety, while the outer sheath is constructed from low smoke zero halogen (LSZH) material, minimizing toxic emissions and smoke in the event of a fire. The cable is further reinforced with galvanized steel wire armor (GSWA), offering exceptional mechanical protection against physical damage, moisture, and harsh environmental conditions.
**Application:**
This instrumentation cable is ideally suited for use in critical industrial applications where multiple signal transmissions and high safety standards are required. It is particularly suitable for industries such as oil and gas, power generation, and industrial automation, where electromagnetic interference and challenging operating conditions are common. The LSZH sheath makes it an excellent choice for confined spaces like tunnels, subways, and buildings, where fire safety and low toxicity are paramount. The GSWA provides added durability, making it perfect for installations exposed to mechanical stress, outdoor environments, or areas prone to physical damage. With its 20x2.5 mm² configuration, this cable is designed for low-voltage instrumentation, control, and monitoring circuits, ensuring stable and interference-free performance. Its robust construction, advanced shielding, and fire-resistant properties make it a reliable choice for industries that prioritize safety, durability, and precision in complex and demanding environments.
