<br> FIG. 18 shows a plot 1800 of DMA measurements (storage modulus versus temperature) for uncured and fully cured pure XLPE in addition to pure PP, uncured XLPE/PP 75/25 and uncured XLPE/PP 50/50 wt % blends. In such an example, the protecting layer is usually a cushion layer that may be an extruded cushion layer that includes XLPE and optionally a number of extra supplies (e.g., PP, talc, carbon black, and so on.). For instance, an electric submersible pumping system can embrace an electric submersible pump that includes an electric motor and a pump
