A spiral (serve) shield lays tinned copper wires in one helical direction; a braided shield interweaves them. Compared on TEBAOFLEX factory samples, with braid coverage explained and a specification checklist.
EPR insulation is the cross-linked ethylene propylene rubber inside mining, reeling, locomotive and portable cables. How it compares with XLPE and XLPO, and which to specify by duty.
Learn what automotive wire is, how GXL and TXL compare, why moisture can wick through stranded copper, and what to specify for a vehicle harness.
Learn what SO cord means, where it is used, and how to read type, AWG, conductor count and voltage markings, with a sample photo and a labeled example.
SOOW, SJOOW and SEOOW are all UL 62 portable cords. The J changes the voltage, the E changes the compound, and neither changes the ampacity. What each letter means and how to choose.
PR I is a 96-hour oil immersion, PR II is 1,440 hours with a higher pass mark. What the two UL ratings prove, and how to specify oil duty.
Silicone, PTFE, PFA, FEP and mica-glass compared by what limits each in service, and why the conductor plating often sets the real temperature ceiling.
The jacket almost always fails before the conductor does. How CPE, TPU/PUR and PVC compare for abrasion duty, how it's tested, and how to match the construction to trailing, reeling or guided routes.
What each letter in RFOU and BFOU actually names, how (i) and (c) screening differs, and which IEC 60092 part belongs on the datasheet. Send the S-code for a quotation.
Armoured mining cable belongs on static routes: mine distribution, substation feeders, shaft risers and roadway supplies. What that changes, and why mining armour is pliable rather than rigid.
