Railway Traction Equipment OCS

OCS is the core power supply equipment in power supply system of electrical railway traction. Its function is to supply power to the running electric locomotive incessantly. Different from the ordinary power transmission line, it must be fixed on the right top of the rail, and then locomotive can get power incessantly through the slip friction between top pantograph and contact wire. So everywhere that electric locomotive running through should span catenary. All catenary installation is hypaethral and it is always affected by kinds of bad weather, as well as its working state is changed with the running of electrical locomotive and has no standby, so working environment for catenary is complex and the request for it is higher. OCS components manufactured by SAITONG introduces and adopts international advanced technology, and optimize the design of key components products according to the technology feature of domestic rail transportation and feature of parallel products. The whole series of products have been homebred, and this caters to the construction and operation of Chinese rail transportation better. Aluminum alloy and copper alloy are adopted much in our product forging, now we have two forging line, and the manufacturing capability hits 2000kms/year. SAITONG is making the core components of Siemens Re250km/h and Re350km/h in China and can produce all catenary components refer to Chinese railway standard; we have passed the test of P.R.C catenary components inspection station. we have the sales ability.

Functional Features
Application and Scope
Cantilever steady equipment is used to locate contact wire in electrical railway canetary system. The material of cantilever can be charry-steel and aluminum alloy. Flat Cantilever composes the angle top of hinged cantilever structure, one end of flat cantilever support canetary through the messenger wires supporting clamp, and the other end is joint with strut insulator. Inclined cantilever supports the flat cantilever with binaural sleeve and the other end is joint with strut insulator. Typical installation structure as follow.
1. Cantilever
When the cantilever is made of carbon steel, seamless steel pipes which refer to the standard of GB/T8162 can be used, while the cantilever is made of aluminum alloy, alma Ilium pipes AlMgSilF31 that refer to the standard of DIN 9107 can be used.
Its min. horizontal breaking load is not less than 24.17kN, and min. vertical breaking load is not less than 15.0kN.
2. Inclined Cantilever binaural sleeve
Inclined Cantilever binaural sleeve is stable at the end of inclined Cantilever to join inclined cantilever and flat cantilever. It is made of the material of cast aluminum alloy EN AC-AlSi7Mg0.6 that refer to the standard of DIN EN 1706 and made by metal mould forging technology. Its working load is not less than 4.0 kN, the min. breaking load is not less than12.0kN, and tightening torques of clamp bolt is not less than 50Nm.
3. Canetary supporting clamp
Canetary supporting clamp is stable at flat cantilever to support and fasten copper alloy canetary that the cross-section is about 70-120 mm2.The top of it is used to support stable line and siding canetary,it can rotate around the horizontal axis free. Canetary supporting clamp is made of the material of cast aluminum alloy EN AC-AlSi7Mg0.6 that refer to the standard of DIN EN 1706,and made by metal mould forging technology. The working load is 6.0kN; the min. breaking load is less than 18kN; Tightening torques: 56Nm for bolt M12, and 70Nm for bolt M16U.
4. Cantilever support
Cantilever support fixes and supports flat and inclined cantilever, it joins with flat and inclined cantilever through Cantilever support binaural sleeve. Cantilever support can be made of carbon steel and aluminum alloy. When the cantilever support is made of carbon steel, seamless steel pipes GB/T8162 can be used, but when the cantilever support is made of aluminum alloy, alma Ilium pipes AlMgSilF31 that refer to the standard of DIN 9107 can be used. Its working load is not less than 9.4 kN; the min. breaking load is not less than28 kN.
5. Steady ring
Steady ring is fixed on the cantilever, it provide installation support to binaural sleeve components, such as cantilever support binaural sleeve and inclined cantilever. Steady ring is made of the material of cast aluminum alloy EN AC-AlSi7Mg0.6 that refers to the standard of DIN EN 1706, and is made by metal mould forging technology. The working load is 5.0 kN; the min. breaking load is not less than15 kN; Tightening torques: 70Nm for bolt M16U.
6. Steady Tube, Hook end fitting
Registration arm provides location support to positioner; one end is joint with registration arm while on the other end pipe cap is installed.
Hook end fitting is fixed in the bottom of registration arm to make it join with inclined cantilever.
Registration arm can be made of carbon steel and aluminum alloy. When the Registration arm is made of carbon steel, seamless steel pipes that refer to the standard of GB/T8162 can be used, but when the Registration arm is made of aluminum alloy, alma Ilium pipes AlMgSilF31 that refers to the standard of DIN 9107 can be used.
Hook end fitting is made of the material of cast aluminum alloy EN AC-AlSi7Mg0.6 that refers to the standard of DIN EN 1706, and is made by metal mould forging technology.
The working load is 2.5kN; the min. breaking load is not less than 7.5kN; Tightening torques: 70Nm for bolt M16U.
7. Steady Arm
Steady Arm has below three kinds, straight, angle and curved steady arm. It is used for clamping the contact wire and ensuring the wire is fixed towards the direction of the line under the request of design. In overlap and curve section of the line, angle and curved steady arm and corresponding bracket will be used.
Steady ear, hook end fitting, grooved stud and rectangular pipe are main components of Steady Arm.
Positioner uses CuNi2Si material that refers to the standard of EN 12165.
Hook end fitting uses EN AW-6082 material that refers to the standard of EN 755-2.
Rectangular pipe uses EN AW-6082 material that refers to the standard of EN 755-2.
Hook end fitting, grooved stud cover and Steady ear are produced with precision casting process for metal mold.
Its working load is 3.5kN and the minimum anti-destroy load is not less than 10.5 kN.
8. Drop bracket
Drop bracket is installed on the registration arm with U style bolt, and the hook at the bottom of it is used for the link of hook end fitting. The position of the steady arm can be adjusted by changing the location of U style bolt on registration arm.
Positioner bracket uses EN AW-6082 materials that refer to the standard of EN 755-2 and are made by metal mould forging technology.
Its working load is 3.5kN and the minimum anti-destroy load is not less than 10.5 kN.
