The SGO-O and SGS-D graphite greases are used for coating pantograph pans of elec-trical rolling stock equipped with metal current-collecting plates to reduce the wear of the plates and contact wire. Depending on the application conditions, the following grease grades are offered: SGS-O GRAPHITE grease – basic compound; SGS-D GRAPHITE grease – additional com-pound. The SGS-O and SGS-D GRAPHITE greases are produced from graphite bonded with coal or pyrolytic tar. SGS-D contains a solvent addi-tive. They are produced from high-quality mate-rials at one of the most up-to-date production facilities in the CIS.
Special Purpose Grease
The SGS-O and SGS-D GRAPHITE greases are used for coating pantograph pans of elec-trical rolling stock equipped with metal current-collecting plates to reduce the wear of the plates and contact wire. The greases can oper-ate all year round in all climatic areas. The SGS-O GRAPHITE grease is used for fill-ing the gap space between the current-collecting plates. Filling is performed with heated lubricating grease, which then hardens during cooling. The SGS-D GRAPHITE grease is used for graphitization recovery of the current-collecting plates and for filling dents, cracks and other de-fects emerging in the SGS-O layer during opera-tion. The grease hardens as the solvent evapo-rates and eliminates the defects of the basic compound layer.
- Wide operating range of the greases, their good frost and heat resistant properties allow them to be used all year round in all climatic zones;
- Excellent anti-wear properties of the greases ex-tend the service life of the devices and equip-ment significantly;
- The greases are effective in protecting friction surfaces from tear, jamming and welding;
- The greases prevent penetration of aggressive liquids and gases, as well as abrasive particles, to the friction surfaces.
