Engineering, implementation and service – power-generation and chemical industry
Our engineering includes the preparation of complete project documentation for electrical equipment, M&C, electronic fire alarms, GDS and CCTV. We always adapt the project structure according to the customer's requirements.
The basic project structure includes especially:
- Technical report
- List of measuring circuits and instruments
- Data sheets
- Hook-Up drawings
- Technical business specifications
- Wiring diagrams
- List of cables
- Terminal board diagram
- Bill of materials
- Disposal
Electrical Wiring of Buildings
Our company also deals with electrical wiring of buildings, especially designing and realizing EPS (Electronic Fire Alarms), GDS (Gas Detection Systems) and TSFO (Physical Protection System). Consequently, we service these devices.
Engineering – shipping
Our engineering services also include the preparation of wiring diagrams and project documentation for electrical and M&C systems for container cranes, especially gantry and grab cranes. We provide these services in cooperation with a German partner company specialising in the implementation and commissioning of such machinery.
All cranes are powered from the 6 kV grid, in which the voltage is further transformed using HV transformers to 500 V AC and 400 V AC. Large motors (cable winches) are controlled by frequency converters with 700 V DC power supply, comprising of ISU LCL rectifiers. Other drives are protected by standard motor protection and controlled through contactors. Because the cranes must be safety category 3 compliant, the required parts are controlled using an ABB AC500 control safety system. An ABB AC800 is used as the main control system. All control elements, sensors and transmitters are integrated into the system, in which everything is controlled through SW. All control elements are installed in distributor cabinets, located in the substation at individual locations.
