FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What is the purpose of the 2×1.5 mm² monitoring cores in SUBCAB Power and Monitoring?
Heavy submersible wastewater, dewatering and slurry pumps incorporate internal stator thermal switches (PTC thermistors or Klixon bi-metal switches) and oil-housing seal-leakage probes (FLS/CLS). Integrating the 2×1.5 mm² control cores inside the main power cable eliminates a second cable entry gland on the pump hood and prevents thin sensor leads from snapping during pump retrieval.
How deep and in what liquids can SUBCAB be permanently submerged?
The cross-linked 3GI3 EPR core insulation and heavy-duty chlorinated elastomer (CSM/PCP) outer sheath are rated for Class AD8 continuous submersion down to 500 m water depth (50 bar) at water temperatures up to +70 °C in fresh water, municipal sewage, industrial sludge and seawater across pH 3 to 10.
Why is outer diameter tolerance critical on submersible pump cables?
Submersible pump cable entry assemblies rely on compression elastomer grommets to seal against 10–50 bar of hydrostatic head. SUBCAB is extruded with a solid inner bedding and tightly controlled circular outer diameter so it seals reliably in standard pump entry glands.
What if my submersible pump operates at medium voltage (3.6/6 kV or 6/10 kV) or requires steel wire armour?
For deep mine dewatering shafts or medium-voltage submersible pumps where high vertical tensile load or rock-fall protection is required, select our NTSCGERLWÖU Armoured Submersible-Pump Cable (3.6/6 kV and 6/10 kV).
