Screened cables are commonly referred to as Variable Speed Drive cables (VSD cables) or Electro Magnetic Compatibility cables (EMC cables).
Protect Your Drives. Eliminate Electrical Noise.
Our screened cables, commonly known as Variable Speed Drive (VSD) or Electromagnetic Compatibility (EMC) cables, are essential for modern industry. They are specifically engineered to protect sensitive drives, PLCs, and control networks from disruptive electrical noise.
The TOPDRIVE range is your premium, high-performance solution, designed for 100% electromagnetic compatibility in Australia’s toughest conditions.
The Challenge: Interference from Variable Speed Drives
Variable Speed Drives are critical for controlling motor speed and saving energy. However, they also create significant electrical “noise” (EMI). When standard power cables are used, this interference radiates outwards, causing major problems:
- Corrupted data in control and sensor cables
- “Ghost” faults and random trips in PLCs and automated systems
- Signal loss and network unreliability
- Premature failure of motor bearings from stray currents
The Solution: TOPDRIVE Symmetrical VSD Cables
TOPDRIVE cables are not standard power cables. They are a specialist solution engineered with two key objectives: contain the noise and protect the motor.
By capturing and neutralising EMI at the source, our cables ensure your VSDs, and all surrounding equipment, operate reliably and as intended.
Key Technical Specifications
This is how TOPDRIVE achieves superior performance:
- 100% EMI Shielding (Double Screen)
A dual-screen construction, featuring both an aluminium-polyester tape and a tinned copper braid (80% coverage), provides total shielding. This double protection is highly effective at neutralising both low and high-frequency interference.
- Symmetrical (3+3G) Earth Conductors
The symmetrical (3+3G) ground conductor design is critical for VSDs. It balances circuit-to-ground capacitance, which mitigates damaging motor bearing currents and voltage imbalances that lead to premature motor failure.
- High-Performance XLPE Insulation
Rated for a maximum conductor temperature of 90°C, our Cross-Linked Polyethylene (XLPE) insulation offers superior electrical stability, higher current carrying capacity, and better thermal performance than standard PVC.
- Rugged LSZH Outer Sheath
The outer sheath is a robust, UV-resistant, and flame-retardant Low Smoke Zero Halogen (LSZH) polyolefin. This ensures maximum safety in the event of a fire (no corrosive gases) and maximum durability for harsh industrial environments.
- Flexible Class 5 Conductors
Finely stranded tinned copper conductors make the cable highly flexible, simplifying installation in tight switchboards, cable trays, and conduits
