Automobile alternators GG273Â1-3 and modifications Print

                                                              

Nominal voltage - 28V, maximum current -45À. 

There are 5 modifications which differ in the dimensions of pulleys. Modifications GG273V13.03 and

GG273V13.04 are equipped with a rectifying block with limiting diodes

 

The alternator is applied to trucks MAZ, KAMAZ, GAZ as an energy resource in the truck’s electric system.
The following types of alternators series GG273B1-3 are produced by «Radiovolna»:

Alternator GG273Â1-3

 The alternator is applied to trucks GAZ 3308,3309. It was launched in 2006 to substitute analogous alternators 5101.3701, 5107.3771 produced by “ZiT”, Samara. The mounting dimensions are identical with the dimensions of the analogous alternators 5101.3701 and 5107.3701. The current output of alternator GG273Â1-3 at minimal rotational speed is 20% higher as compared to analogous alternators 5101.3701, 5107.3701. The maximum rate of current output of alternator GG273Â1-3 is higher than that of analogous alternators 5101.3701, 5107.3701 (45À instead of 35À).                                                                   

Alternator GG273Â1-3.01

The alternator is applied to trucks MAZ, KAMAZ with engines YaMZ-236,238 and KAMAZ-740 instead of our alternator GG273Â1, the alternator G273Â1 produced by ZiT, Samara, as well as the alternators 1322.3771 produced by ATE-1 PRAMO è 3232.3771 produced by BATE, Borisov. The current output of alternator GG273Â1-3.01 at minimal rotational speed is 50% higher. The working life of the alternator until the 1st extensive repairs is 17% higher. The quality is much higher (250ÐÐÌ) thanks to using components of better quality.

Alternator GG273Â1-3.02

 The alternator is applied to trucks MAZ-4370 with engines D260, D245 instead of our alternator G9945.3701-01, as well as the alternator 3232.3771 produced by BATE, Borisov. The current output of alternator GG273Â1-3.02 at minimal rotational speed is 50% higher as compared to analogous alternators. The working life of the alternator until the 1st extensive repairs is 17% higher. The quality is much higher (250ÐÐÌ) thanks to using components of better quality.
