RSTI Separable Connectors play an important role in safe and reliable medium-voltage cable installations. Across oil and gas facilities, power generation plants and electrical distribution networks, dependable cable connections help keep critical equipment running. Therefore, choosing the right cable accessories is essential for every project.
Here, at Eunisell Interlinked Plc, we provide RSTI separable connections for medium-voltage cable installations across power generation, transmission and distribution infrastructure. In addition, our cable accessory solutions support the needs of international oil companies, indigenous oil and gas operators, EPC contractors and power utilities.
Whether you are developing a new facility or upgrading an existing electrical network, the right connection solution can make a real difference.
What Are RSTI Separable Connectors?
RSTI separable connectors are screened cable connection accessories designed for medium-voltage electrical systems. They connect single-core and three-core polymeric cables to electrical equipment such as transformers, ring main units (RMUs) and switch gear.
Moreover, these connectors form an important part of modern power distribution systems. They also provide a compact connection arrangement where installation space may be limited.
Also, Raychem RSTI connectors from TE Connectivity feature highly modified silicone rubber insulation and a grounded outer conductive screen. As a result, they support screened connections in both indoor and outdoor installations.
Depending on the product model, the RSTI range offers solutions rated up to 42 kV and 1250 A.
Why RSTI Separable Connectors Matter in Oil and Gas Operations
However, oil and gas facilities depend on stable electrical systems. From production sites to processing plants, every critical electrical connection must meet the demands of its operating environment.
Therefore, selecting suitable medium-voltage cable accessories is an important part of project planning.
Also, RSTI separable connectors offer several useful features for these applications.
1. Compact Design for Limited Installation Space
Electrical installations do not always provide generous working space. For example, switch gear compartments and transformer connection areas can have tight layouts.
Thus, RSTI connectors feature a compact design. Consequently, they help engineers work within limited terminal spaces while maintaining a suitable connection arrangement.
2. Screened Protection
Electrical safety is a major concern across oil and gas facilities.
Hence, RSTI connectors feature an outer conductive screen that connects to earth. This design provides a fully screened connection system when correctly installed and earthed.
As a result, the connectors support safer equipment integration and help protect the connection from external environmental exposure.
3. Flexible Application Options
Thus, different projects require different cable sizes, conductor materials and equipment interfaces.
Fortunately, the RSTI product range offers options for various cable configurations. Depending on the selected model, these include copper and aluminum conductors, as well as different cable cross-sections and voltage ratings.
In other words, this flexibility helps project teams select suitable connection accessories for their installation requirements.
4. Capacities Test Point Options
Some RSTI connector models include a capacities test point.
For this reason, this feature allows trained personnel to check for voltage presence using suitable testing equipment and approved procedures.
Therefore, it can support maintenance activities and electrical safety procedures. However, it does not replace proper isolation, testing and earthing requirements.
Applications of RSTI Separable Connectors
RSTI separable connectors support several medium-voltage electrical applications.
These include:
- Oil and gas facilities: Medium-voltage connections for electrical distribution systems in production, processing and supporting facilities.
- Power generation plants: Cable connections between generators, transformers and associated switch gear.
- Transmission infrastructure: Suitable equipment connections within medium-voltage sections of wider transmission networks.
- Power distribution networks: Connections for transformers, RMUs and medium-voltage switch gear.
- Industrial facilities: Electrical connections for plants, processing facilities and other industrial installations.
- Offshore and marine projects: Suitable RSTI variants for approved marine and offshore applications.
Therefore, in each case, correct product selection remains essential. Engineers must confirm the voltage rating, bushing interface, cable dimensions and applicable project specifications before installation.
RSTI Separable Connectors for EPC Contractors and Project Engineers
For EPC contractors, reliable electrical components are important at every stage of project delivery.
Also, from engineering and procurement to construction and commissioning, the quality of cable accessories can affect installation quality and long-term equipment performance.
Hence, RSTI separable connectors provide a practical connection option for compatible medium-voltage equipment.
Furthermore, their compact design and range of configurations can help project teams address different installation requirements.
For this reason, EPC contractors and electrical engineers should consider the following before procurement:
- Confirm the system voltage and current requirements.
- Check the cable insulation diameter and conductor cross-section.
- Verify the equipment bushing type and rating.
- Confirm compatibility with copper or aluminum conductors.
- Review the manufacturer’s installation instructions.
- Ensure that qualified personnel carry out installation and testing.
Because, by checking these details early, project teams can reduce product selection errors and improve installation planning.
