With rising demand for power all over the world, underground transmission systems are being installed at an ever-increasing rate. Dow Electrical & Telecommunications has developed a complete portfolio of insulation, semiconductive and jacketing compounds that are ideal for wet and dry design underground High Voltage (66kV to 220kV) cables and Extra High Voltage (220 kV to 500 kV) cables. These products have already been proven in underground transmission systems across Europe, providing long-term reliability at a lower total system cost over the lifetime of the installation.
