German Equipment in Havana 



Some imusual features have been em- 

 bodied in the 4,500 horse-power generat- 

 ing station constructed recently by the 

 AUgemeine Elektrizitatsgesellschaft, Berhn, 

 Germany, for supplying electrical energy to 

 the City of Havana, says the N.Y. Electrical 

 World. The power house, situated out- 

 side the city immediately on the sea, shows 

 Some striking constructive features depend- 

 ent on the extraordinary favorable climatic 

 conditions in a country where the tempera- 

 ture never falls below 16 deg. C. In fact 

 the boiler-house is completely open on the 

 side turned towards the stoker's stand, the 

 sheet-iron flue being carried above the 

 boiler-house to the chimney. On account of 

 this arrangement the economizer serving 

 to preheat the boiler feed-water has been 

 installed on the roof of the boiler-house. 

 The latter, as well as the engine-house, 

 and its accessory rooms, are mainly made 

 of iron blocks formed on the spot. All 

 of the materials, inclusive of the bricks 

 used for the stack, have been imported 

 from Germany. 



The boiler-house contains four marme 

 type water-tube boilers designed by a Lon- 

 don firm, each of which has a heating area 

 of 300 sq. m. (3,200 sq. ft.) in contact with 

 water, and is fitted with a superheater rais- 

 ing the temperature to 3.50 deg. C. 



The generating plant comprises four 

 1,100 horse-power, 6,000 volt, three-phase 

 generator sets, which are excited from a 

 small storage battery, or a 48 kw. motor- 

 generator. 



The switchgear is designed on the trans- 

 portable switchboard system. The three- 

 phase energy is supplied through a cable 

 system about 50 km. (30 miles) in length, 

 laid partly in clay pipes, to a number of 

 oil insulated transformers located in un- 

 derground cabins of 2,160 kw total rating, 

 where the e. m. f. of the high-tension 

 energy is lowered to the working value of 

 220 volts. The low-tension conductor sys- 

 tem which is likewise designed as a cable 

 system then distributes the energy to the 

 various centers of consumption. 



iVdmission of Cuban Title 



In a letter on August 20th to the Ceutral 

 Association of the Isle of Pines U. S. 

 Minister Jackson, replying to a communica- 

 tion from the association asking him to 

 use his influence to restore American 

 schools, took occasion to make the follow- 

 ing important statement : "The United 

 States has recently appointed an American 

 Consular Agent at Nueva Gerona. — This 

 constitutes in my opinion, a more direct ad- 

 mission to Cuban title to the Isle of Pines 

 than had heretofore been made."
