Remote bus cables

Standard remote bus cable Remote bus cable for special applications

Fig. 4/26 Standard remote bus cable Fig. 4/27 Remote bus cable with additional armouring

Application

Coaxial cable 2YC(mS) CY1.6/10-75(Z2/5) vs sw is used as standard as the remote bus cable. The cable may be routed in potentially explosive atmospheres to DIN 57 165/VDE 0165, Section 5.6.1 and is also suitable for burial in the ground. Max. permissible length 4000 m.

Coaxial cable 2YC(ms)CY 1.0/6.5--75(Z2/5)vs ws (in-house cable) can be used indoors. Max. permissible length 2000 m.

Design

From inside to outside:

- Cu conductor, silver-coated	- Plastic film
- Polyethylene isolation	- Braiding of Cu wires
- Braining of Cu wires	- PVC sheath, black, wall thicknes
- Plastic film	- approx. 1.8 mm.
- Winding of metal ribbon

Calculation of the max. permissible length of the remote bus cable when using the standard and in-house cables together:

LF= 4000 m -- 2 Li

where Li Length of in-house cable in m; max. 2000 m LF Length of remote bus cable in m

Application

The cable 2YC(mS)CYbY1.6/10-75(Z2/5) vs (F 0.8 vzk) sw (Order No. V45466-D21-B65) must be used if the tensile strength of the standard remote bus cable is insufficient. This has additional armouring to increase the tensile strength of the cable to 25000 N.

If protection against damage by rodents and mechanical dam- age is required, the cable 2YC(mS)CYbY1.6/10-75 (Z2/5) vs (2 B 0,5 vzk) sw (Order No. V45466-D21-B55) with additional steel-tape armouring should be used. This cable does not have an increased tensile strength.

Design

Both cables have the same basic design as the standard re- mote bus cable (see there) but have additional armouring.

Max. permissible length of remote bus cable: see standard cable.

Buried laying of the remote bus cable

The remote bus cable must be laid in sand and covered with a suitable mate- rial, e. g. concrete or plastic slabs. The cable should be laid on a 10-cm thick layer of sand and then covered with another 10 cm sand. A cable for poten- tial equilization must be laid above the remote bus cable.
