RVV And TRVV Are Two Different Cable Models

RVV stands for copper core PVC insulated PVC sheathed flexible cable. Its specifications include 4x6mm2 flexible cable, cable flexible 2x0.75mm2, 2x6mm2 flexible cable, 2.5mm 3core flexible cable, etc.
 

TRVV stands for copper core PVC insulated PVC sheathed flexible cable for drag chain.It can be seen from the cable model that TRVV is more suitable for mobile use in drag chain systems than RVV. TRVV is a drag chain cable, while RVV is an ordinary flexible cable.

This alone determines the difference between cable RVV and TRVV. Whether it is copper core conductor or PVC insulation and sheath, although the materials seem to be the same, they are essentially different.
 

Cables of the same specification RVV and TRVV, TRVV conductor has a smaller amount of copper wire.
In addition to the softness of RVV, the insulation and sheath materials of cable TRVV also have toughness and wear resistance, and have better flexibility and mechanical properties.

Fine raw materials also determine the price difference between TRVV and RVV. The price of TRVV drag chain cables is also higher.
In application, there is no actual cable RVV or TRVV which is better, only which cable is more suitable. Flexible cables for fixed installation, 2core 1.5 sqmm flexible cable, 4 core, 16sqmm flexible cable, and
