With over 60 years of experience in cable manufacturing, Tratos offers not only advanced cables but also professional termination services. Our expertise ensures that every termination — whether Low, Medium, or High Voltage, or fibre optic — is executed with precision, reliability, and durability, guaranteeing high-performance connections in the most demanding environments.
Termination Reeling Cable
Reeling cables operate in some of the most demanding conditions in the cable industry. Unlike fixed installations, these cables are in constant motion — subjected to continuous bending, torsion, and mechanical tension. Terminations must therefore be engineered to withstand these stresses while guaranteeing safe and reliable electrical or optical performance throughout the life of the system.
Medium Voltage (MV) Terminations for Reeling cables
The termination of MV reeling cables requires specialist techniques and components to manage both electrical and mechanical challenges.
Key Requirements
- Stress Control – Proper stress cones (heat-shrink, cold-shrink, or pre-moulded) ensure smooth electrical field distribution at the screen cut, preventing partial discharge and surface tracking.
- Mechanical Anchorage – Conductors, armour, and sheath must be securely clamped so that mechanical loads are not transferred to the insulation.
- Sealing – Robust environmental barriers protect against the ingress of water, oil, dust, and other contaminants common in reeling applications.
- Flexibility – The termination must tolerate repeated winding and unwinding cycles without compromising electrical integrity.
Why Tratos?
- Extensive experience in designing and terminating MV reeling cables for ports, mining, offshore, and industrial sectors.
- Certified jointers applying precise stripping and preparation techniques to protect insulation integrity.
- Proven solutions that deliver long service life under continuous dynamic stress.
Fibre Optical Terminations for Reeling cables
Hybrid and fibre-only reeling cables demand equal precision, as optical fibres are highly sensitive to bending and tension. Tratos ensures that every termination preserves signal integrity even in extreme operating conditions.
Key Requirements
- Strain Relief – Fibres are terminated so that mechanical forces are absorbed by the strength members, not the optical elements.
- Connectorisation / Splicing – Fibres are routed into splice trays or connectors within vibration-resistant housings, minimising losses and ensuring low attenuation.
- Sealing & Protection – IP-rated housings and gel seals protect sensitive fibres against dust, moisture, and vibration.
- Dynamic Performance – Terminations maintain alignment and optical continuity throughout repeated reeling cycles, preventing microbends and signal degradation.
Why Tratos?
- Specialists in hybrid reeling cables that combine power and fibre optic cores.
- Full termination service from splicing to connectorisation, tested to international fibre standards.
- Proven in marine, offshore, and industrial applications where continuous reeling demands uncompromising reliability.
Conclusion
Reeling cable terminations — whether medium voltage power or fibre optic — require a unique blend of electrical, mechanical, and environmental protection.

Termination Medium Voltage Cable
The termination of Medium Voltage (MV) cables is critical to the reliability of modern distribution networks. MV cables, typically rated from 1 kV up to 36 kV, connect substations, industrial plants, and infrastructure assets, making the quality of each termination vital for safety and operational continuity.
Key Functions of MV Terminations
- Electrical Stress Control: At the point where the insulation and conductive screen are cut back, the electric field must be carefully graded. Stress control components (heat-shrink, cold-shrink, or pre-moulded) are installed to prevent partial discharge and dielectric breakdown.
- Environmental Sealing: Terminations must prevent moisture ingress and contamination. Indoor terminations use compact sealing systems, while outdoor solutions incorporate polymeric weather sheds to extend creepage distance and resist pollution and wet conditions.
- Mechanical Anchorage: Conductors, metallic screens, and armour must be properly clamped to prevent mechanical loads from affecting the insulation. Correct earthing of metallic layers ensures system safety.
- Safety & Reliability: Properly executed MV terminations protect equipment, personnel, and service continuity by reducing the risk of flashover, overheating, or insulation failure.
Types of MV Terminations
- Indoor Terminations – Compact terminations without weather sheds, designed for use in controlled environments such as switchgear, transformers, and substations.

Termination Low Voltage Cable
Low Voltage (LV) cable terminations, typically up to 1 kV, are fundamental to the safe and efficient performance of power distribution systems. While the electrical stresses are lower than in medium or high voltage systems, poor workmanship or incorrect components at termination points can lead to overheating, energy losses, or fire hazards. Each type of LV cable requires specific termination methods to ensure mechanical stability, electrical continuity, and environmental protection.

Termination Fibre Optical Cable – Installation
The termination and installation of fibre optic cables are critical to the performance of modern communication, monitoring, and control systems. Unlike power cables, fibre optic terminations must not only provide mechanical stability and environmental sealing but also preserve the optical characteristics of the fibres, ensuring low attenuation, high bandwidth, and signal integrity over long service lifetimes.
Key Functions of Fibre Optic Terminations
- Optical Continuity – Terminations must provide precise alignment of fibre cores to minimise insertion loss and back reflection.
- Strain Relief – Strength members are anchored to absorb pulling forces, ensuring no stress is transferred to the delicate optical fibres.
- Environmental Protection – Sealed housings prevent dust, moisture, and vibration from degrading optical performance.
- Dynamic Stability – For installations in industrial, offshore, or reeling applications, terminations must tolerate movement without introducing microbends or signal degradation.
Installation Considerations
- Connectorisation & Splicing – Fibres can be terminated with connectors (LC, SC, ST, MPO, etc.) or fusion-spliced into pigtails, depending on system requirements. Fusion splicing is preferred for low-loss permanent joints.
- Patch Panels & Enclosures – Terminated fibres are housed in patch panels or splice trays designed to provide bend-radius protection and facilitate future maintenance.
- Testing & Certification – Following termination, cables are tested using OTDR (Optical Time Domain Reflectometer) and power meter methods to confirm compliance with attenuation and reflection limits.
- Installation Environments – Fibre terminations must be adapted to their location, whether in protected indoor cabinets, outdoor street cabinets, or harsh offshore and reeling applications.
