Great flexibility to achieve the leakage distance values through outer insulator rings, shortening the length of the arrester body. Its silicone enclosure is greatly hydrophobic and UV resistant; it limits leakage currents, eliminates the costs of washing and can increase the life of the equipment. They can be used in highly polluting environments. Certified and approved by the CFE (LAPEM) laboratories. Applicable Standards: IEC NMX-J-321-ANCE. NERF-004-C.F.E.

Opposed to conventional arrestors, these are disconnected from the distribution line by an air gap that allows controlling the discharges it extinguishes, as demonstrated in the tests performed, which obtained satisfactory results according to specification CFE The design of its silicon rubber sleeve ensures that the arrestor will not release highspeed solid residues and is compliant to be installed under normal and high pollution environmental conditions.

24 IUSA Protection Transformers and Disconnection Equipment for High and Medium Voltage and Transformers TRANSFORMERS II. POST TYPE IUSA Prisma Phase Converter Post-Type The PRISMA phase converter operates by delivering three-phase electric power from a single-phase source. It operates in medium voltage with two phases, two wires, and provides in low voltage three-phase voltage values on four wires. This differentiates the PRISMA IUSA phase converter from transformers, selftransformers, or converters, whether electronic, with capacitors, or of the generator type. Our converter behaves as a voltage source connected at medium voltage to an infinite bar (as could be the medium voltage terminals from the power supply company at 33kV, 25kV, 15kV), limiting the power delivered to working elements of the equipment, delivering three-phase power on the low voltage side (it is reversible). Thus, three-, two-, or single-phase loads resistive, inductive, or capacitive can be connected to its output terminal blocks at any secondary voltage value used worldwide. IUSA Prisma Phase Converter Post-Type CLASS Primay voltage volts volts volts Secondary voltage It can be: 440/254 volts, 380/220 volts, 220/127 volts, or any that is necessary. Frequency 60 Hz Overheating 65 or 55 C for warm climate Operating altitude 2300 meters above sea level Type of cooling OA Surge protection None on post type Medium voltage terminals Bushings with ring terminals according to the voltage required. Low voltage terminals Low voltage bushings with ring terminal. Specification PRISMA IUSA phase converter for distribution, post type and substation type (ETO-120-2/3, 240-2/3).
