[vc_row][vc_column width=”1\/1″][vc_accordion collapsible=”yes” disable_keyboard=”” style=”2″ el_class=”accordion-ficha”][vc_accordion_tab title=”GENERAL INFORMATION”][vc_column_text]Self-protected or anti-theft distribution transformers are suitable to rural and urban zones.<\/p>\n

The Distribution rural transformers are single-phase CHEMEL type, they can count on one or two high voltage insulators and they have a fuse incorporated.<\/p>\n

    \n
  1. GENERALITIES <\/strong><\/li>\n<\/ol>\n

    Transformadores CH has developed self-protected rural transformers with a single phase, two-phases or three-phases, with grounding return. In the process of manufacturing of the transformer the costs have been reduced by eliminating those accessories that were no necessary, this without reducing the quality and its functionality.<\/p>\n

    1.1\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Voltage and frequency of self-protected transformer.<\/strong><\/p>\n

    Nominal: 50 or 60 Hz, according to the country.<\/p>\n

    Peru and Brasil:<\/p>\n

    23.000\/231 \u2013 60 Hz.<\/p>\n

    12.000\/231 \u2013 60 Hz.<\/p>\n

    7.620\/231 \u2013 60 Hz.<\/p>\n

    1.2 \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Capacities.<\/strong><\/p>\n

    Self-protected two-phase rural transformers: 3-5-10-15-20 and 25 KVA<\/p>\n

    Self-protected single-phase rural transformers: 1.5-3-5-10-15-20 and 25 KVA.<\/p>\n

    1.3\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Derivations <\/strong><\/p>\n

    Self-protected rural transformers have a full capacity primary side of derivations, able to connect by epoxy changer of operations without voltage, outdoors type protected by weather type.<\/p>\n

    Derivations are according to the country.<\/p>\n

      \n
    1. Constructive details <\/strong><\/li>\n<\/ol>\n

      Design, construction and testing of self-protected rural transformers comply with the norm n\u00ba 76, CEI, about auto-refrigerated transformers immersed in oil that work outdoors.<\/p>\n

      2.1\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Self-protected transformers pond <\/strong><\/p>\n

      It is constructed with wieldable steel and has a sealed bolted cover. The minimum thicknesses is: walls 2,5mm and lid and deep 5 mm.<\/p>\n

      The transformer is protected all its life because its fond is sealed.<\/p>\n

      1.1\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 The transformer is easily fixable because the pole has 2 sealed rucksacks. Self-protected transformer nucleus <\/strong><\/p>\n

      Self- protected transformer nucleus is enrolled, of siliceous steel, of great quality grain oriented that reduces the no load losses.<\/p>\n

      1.2\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Self-protected rural transformers coil <\/strong><\/p>\n

      Self-protected rural transformers coil is made of insulated wire with double layer of enamel. They are designed to guarantee the wide margins of security on insulation, coldness and resistance to high short circuits.<\/p>\n

      1.3\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 High voltage bushing (class 15 KV and 25 KV) <\/strong><\/p>\n

      If there is an internal fault in self-protected or anti-thefts rural transformers, they have an epoxy bushing with high voltage protection incorporated that protects it insulating it from the line it is connected to. This fuse can be changed easily with a pole.<\/p>\n

      1.4\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Low voltage bushing (class 1.2 KV) <\/strong><\/p>\n

      Epoxy bushing that complies with the requirements of the norm for 1,2 KV.<\/p>\n

        \n
      1. Advantages<\/li>\n<\/ol>\n

        2.1\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Anti-vandalism<\/p>\n

        It is because its bushing is in epoxy resin.<\/p>\n

        2.2\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Aseismic self-protected transformers<\/strong><\/p>\n

        It is because its bushing is epoxy and one piece.<\/p>\n

        2.3\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Bushing A.T. epoxy material that substitutes the single-phase disconnectors collocated in wooden crosspiece, in trunk line or in second position, deriving directly from the line to the self-protected transformer, with connected presses with poles.<\/p>\n

        2.4\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Changer of epoxy derivations. <\/strong><\/p>\n

        If the customer wishes it, a protection box and derivation of electrical joints can be added to the self-protected transformer. It is a way to obtain more space and security.<\/p>\n

        2.6\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Street lighting <\/strong><\/p>\n

        For street lighting, it can be equipped with a special system that incorporates photocells in the superior part of the box with an input connector.<\/p>\n

        2.7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Self-protect or rural transformer has a plug wires bar of concentric joints; in the case it is necessary to use this wire. <\/strong><\/p>\n

        2.8\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 The use of anti-theft or rural transformers is 33% more economic. <\/strong><\/p>\n

        2.9\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 The installation of self-protected transformer is cleaner and they take advantage of the spaces of the pole. <\/strong><\/p>\n

        2.10\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 DAE Transformers can be installed in ponds of 8.70 meters. It maintains the minimum altitude for a net A.T. and B.T. required by the norms. <\/strong><\/p>\n

        2.11\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Anti-theft or self-protected transformer is a development of Transformadores CH, which patent is #35450. <\/strong>[\/vc_column_text][\/vc_accordion_tab][\/vc_accordion]
