Why Silicone Gel for Cable Protection?

Cable accessories often face water ingress, condensation, vibration and thermal movement.
Unlike hard potting compounds, silicone gel remains soft after curing. This helps reduce stress on cables and terminals while providing insulation and sealing protection.
For applications requiring later inspection or repair, re-enterable silicone gel can be a more practical solution than rigid encapsulation.
