RHW-2 2 kV 300 kcmil

Description

Description

Standards

  • National
    ASTM B 8; UL 2556; UL 44

Application:

Electrical system in buildings, industrial, mine and commercial. Maximum operating temperature 90°C, in dry or wet locations. Better performance than the XHHW-2 cables in harsh environments.

Construction:

1. Conductor: Compact soft copper, class B.

2. Insulation: Anti-flame cross linked polyethylene XLPE.

Main characteristics:

Offer more insulation thickness and better insulation resistance than the XHHW-2. Resistance to heat, high insulation resistance. Resistance to abrasion and moisture. Sunlight resistance. Resistant to vertical propagation of the flame VW-1. Resistant to horizontal propagation of the flame FT2. Resistant to gasoline GR II according to UL 44.

Gauge:

From 8 AWG up to 600 kcmil.

Marking:

Gauge(Section mm2) E222164(UL) RHW-2 2000 V 90°C INDECO S.A. VW-1 CT SR GR II CMPCT CU - Year - Sequential length.

Packing:

Non returnable wooden reels.

Colour:

Black.

BENDING RADIUS WHEN INSTALLED IN L.V.

R=Dxf

R: Bending radius when installed (mm)

D: Diameter over sheath or over insulation (when it has not sheath) (mm)

f: Multiplicative factor; given the following table:

Bending radius factor LV

Calculation of Current Condition L.V. AWG/kcmil - Single-core 90 °C

BASED ON NEC TABLES 310.16 (IN RACEWAY) AND 310.17 (IN FREE AIR)
Maximum conductor temperature: 90°C.
For ambient temperatures other than 30°C, see tables 310.16 and 310.17, correction factors (NEC).
