Details Cable Structure

• Bare copper conductor, multiple wired acc. to DIN VDE 0295 cl.2 / IEC 60228 cl.2

• Core insulation: XLPE acc. to EN 50290-2-29

• Cores stranded in pairs, triads or quads

• Cores twisted together in cable elements in optimal lay length

• Core identification pairs: BU, BK triads: BU, BK, RD quads: BU, BK, RD, GY blue cores with continuous black numbering

• Cable elements are stranded in optimal lay length

• Overall screen: AL/PE tape over tinned copper stranded drain wire (7x0,3 mm)

• Outer sheath: PVC acc. to EN 50290-2-22

• Outer sheath colour: black or blue

• With meter marking

  Properties

• Low level of line attenuations and low mutual capacitances enable long transmission distances

• Cable elements are produced of non-hygroscopic materials

  Tests

• Flame retardant acc. to DIN VDE 0482-332-1-2/ DIN EN 60332-1-2/IEC 60332-1-2

• Flame test on bunched wires acc. to DIN VDE 0482-332-3-22/ DIN EN 60332-3-22/IEC 60332-3-22 (Cat. A)

• Oil resistant acc. to ICEA S-73-532/ NEMA WC 57

• UV-resistant acc. to UL 1581 section 1200

  Notes

• Alternative denomination: RE-2X(St)Y

• Not suitable for direct burial

• The conductor is metrically constructed (mm2). The AWG designation is approximate and purely informative.

• We also offer cable glands HELUTOP HT-MS-EX-d

  Application

• For the transmission of digital and analog signals in harsh environments like oil, gas and petrochemical industries. The cables are suitable for fixed installation in dry and damp locations, open spaces and in underground networks.
