Overview
The G10-06 is the large-size cover in the G10 terminal insulation series, molded for heavy-duty cable lugs, bolted terminals and bus joints in the 150–300 mm² conductor range. This is the terminal size found on main feeder cables, transformer primary connections, MV switchgear bus joints and large-capacity distribution lines — connections that carry hundreds of amps and represent a significant fault-risk point.
At these current levels, terminal heating accelerates pollution tracking and moisture-driven surface degradation. A bare large terminal in a coastal or industrial environment can develop a conductive pollution layer in months. The G10-06’s thick HTV silicone body provides robust insulation coverage that sheds contamination, prevents tracking-path formation, and eliminates the phase-to-ground clearance vulnerability at the connection point.
Part of the 4-size G10 family — if G10-06 is too small or large, check G10-05 (50–150 mm²) or G10-07 (>300 mm²). Molded from HTV silicone — hydrophobic, UV-stable, anti-tracking, flame-retardant. Slip-on cap design; live-line installable. Custom dimensional adjustments and OEM branding available.

Key Features
Heavy-Duty Coverage
Thick-wall HTV silicone body sized for large 150–300 mm² cable lugs — robust insulation for high-current connections.
High-Current Thermal Stability
Withstands the elevated operating temperatures of heavily loaded feeder and transformer primary terminals without degradation.
Anti-Pollution Shedding
Hydrophobic surface prevents conductive contamination build-up on large terminal surfaces — the biggest tracking risk on MV equipment.
Clearance Enhancement
Adds effective insulation between phases on closely-spaced large terminals where bare-metal phase-to-phase clearance is marginal.
Decades Outdoors
UV-stable, ozone-resistant, -60°C to +200°C — designed for permanent outdoor installation on critical feeder connections.
Full G10 Coverage
One supplier, four sizes — consistent material and quality from your smallest control-wire terminal to your biggest feeder lug.
Applications
Transformer Primary Bushings
Insulating MV primary-side cable lug connections on distribution transformers up to several MVA.
Main Feeder Cable Terminations
Large cable lug covers where underground feeder cables terminate at overhead riser poles or switchgear.
MV Bus Joints
Insulating bolted busbar connection points in MV switchgear and substation bus runs.
Industrial MV Connections
Heavy cable terminations in plant substations, mining switchgear, and large motor feeders.
