What's the Difference between Commscope XAGA 500 and 550 Heat Shrink Closure Systems?

Title: What's the Difference between Commscope XAGA 500 and 550 heat shrink closure Systems?

If you're looking for a reliable and high-quality heat shrink closure system, there’s no doubt that Commscope XAGA series are one of the best. Among the different models available, two of the most popular options are the XAGA 500 and XAGA 550. In this post, we'll take a closer look at these two products and explain their differences.

First, let's start with some basics. Both the XAGA 500 and XAGA 550 are designed to provide environmental protection for non-pressurized spliced or terminated telephone copper cables. They are made of heat-shrinkable polymeric materials that shrink to a pre-determined size when heated, creating a tight and secure seal around the cable. This seal helps prevent moisture, dust, and other contaminants from entering the cable and affecting its performance.

Both these two types of heat shrink closures are supplied with fiber-reinforced heat shrink sleeves with aluminum foil layer structure and other accessories. So, what sets the XAGA 500 and XAGA 550 apart? The main difference lies in the packaging and accessories that come with the products. The XAGA 500 is supplied with a cardboard liner that holds the splice/termination part, as well as other accessories such as PVC tape, mastic sealing strips, and cable ties. On the other hand, the XAGA 550 is supplied with aluminum canisters that contain the closures and accessories.

The packaging and accessories might seem like a minor detail, but they can have important implications for the installation process. For example, the aluminum canisters of the XAGA 550 provide additional protection against physical damage and exposure to UV radiation. This can be particularly useful if the closures need to be stored for a long time or transported to a remote location. In contrast, the cardboard liner of the XAGA 500 might be more suitable for installations where space is limited or where the use of metal containers is prohibited.

Another aspect to consider when choosing between the XAGA 500 and XAGA 550 is their performance in case of fire. As we mentioned earlier, both products are made of heat-shrinkable polymeric materials that contain polyethylene. In complete combustion, these materials release water and carbon dioxide, which are not harmful. However, if the combustion is incomplete, they can produce carbon and other by-products that might be toxic. The XAGA 500 comes with PVC tape that can produce hydrogen chloride gas when burned, which is harmful to the human body. In contrast, the XAGA 550 includes a low-smoke and zero-halogen tape that produces less toxic by-products in case of fire.

In summary, the Commscope XAGA 500 and XAGA 550 heat shrink closure systems are both high-quality and reliable options for protecting cable splices and terminations. Their main difference lies in the packaging and accessories that come with the products, as well as their performance in case of fire. If you're unsure which one to choose, consider the specific needs of your installation and consult with a professional to make an informed decision.
