FAQ

Questions engineers ask first

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

What does Type SGT mean in SAE J1127?
In SAE J1127, 'S' stands for Starter, 'G' stands for Ground, and 'T' stands for Thermoplastic (PVC) full-wall insulation rated for 60 V DC automotive battery service.
When should I choose SGX or STX over SGT?
SGT uses thermoplastic PVC rated up to +80 °C/+105 °C. When routing near hot turbochargers, exhaust manifolds, or tight engine bays requiring +125 °C thermal endurance and zero melt-back during soldering or overload, select cross-linked XLPE Type SGX or thin-wall Type STX.
Why is there a paper separator inside SGT battery cable?
The thin paper separator wrap prevents the extruded PVC compound from keying into the outer rope-lay copper strands, ensuring rapid, clean insulation stripping prior to crimping or soldering heavy-duty battery lugs.
What voltage and temperature ratings apply to SGT under SAE J1127?
SGT is rated for 60 V DC (25 V AC) (maximum operating voltage 60 V DC, dielectric test voltage 1000 V AC (spark/dielectric test per SAE J1127)) and continuous operation from -40 °C to +105 °C (short-circuit up to +150 °C) per SAE J1127.
