TRANSMISSION AND DISTRIBUTION
During the last five years, considerable attention has been given
to the expansion of distributing systems and the extension of hightension
lines with the result that at present there are over 5,000 kilometers
of cables carrying voltages of 10,000 volts and over. The
total distances connected by these cables amounts to over 1,000
kilometers, of which about 15 per cent is located in the Outer
Possessions.
West Java.—-The greatest development in this direction has taken
place in west Java and has been carried out almost entirely by the
Netherland East Indies Government. The outstanding distribution
system in this area is the 70,000-volt line that transmits the output of
the two great water-power stations, Oebroeg and Kratjak, to the
metropolitan district of Batavia, Weltevreden, and Meester Cornelis,
through substations at Buitenzorg and Depok. About 710 kilometers
of 70-millimeter copper cable is used in this 118-kilometer
line. Other important systems in West Java are the following:

The N. I. G. M. and the G. E. B. E. O., the two public-utility
companies marketing electric current in west, J ava, have standardized
the following currents for high and low tensions distribution in their
respective areas.
N. I. G. M., for high tension: 12,000 (volts); 7,000, 6,000, 2,000. For low
tension: 440 (volts), 220/127, 110. ]
G. E. B. E. O., for high tension: 30,000 (volts), 25,000, 6,000. For low tension:
220/127 (volts), 190/110.
Central Java.—There are no outstanding distributing systems in
central Java, the longest high-voltage transmission line being only
about 30 kilometers in lencth. They are listed below:
