Aluminum Thimbles
Crimp-fixed aluminum thimbles, GOST 9581-80, climatic construction
UHLZ, are designed for termination of cables and wires with aluminum conductors
constructed of 16- to 240-mm2 gauge and are designed
for voltages up to 35 kV.
The structure of notational conventions
used for these thimbles, according to GOST 9581-80
Frequently used identifications of aluminum thimbles
utilized in crimping:
1) Letter symbols:
A; TA; Al(o)
"T" stands for 'tube' - the material of which the thimbles are made.
Alternatively, thimbles designed for crimping can be either cast or manufactured
of plain bars. "A" stands for "aluminum": the material
of which the thimble is made. "Al(o)" - Al is the Latin symbol for
aluminum that is used in the periodic table of elements. The "o" letter
in parentheses means that the thimble is designed for crimping.
2) Numerical
symbols:
95-12-13; 95-12; 95; 13

Note:
Because the outer diameter of the sector conductor is more
than that of a normal (round) conductor in the same section, it is necessary to
either round the conductor prior to crimping, or use the thimbles in the next
larger section. For example, with a 95mm²-gauge sector conductor a 120mm²
thimble should be used. | | |
