Heating Cable

nnnn

Self regulating, medium temperature

nnnn

For freeze protection or temperature maintainance up to 150 °C. For use in pipes, valves, tanks, etc.

nnnn

The two copper conductors are located within an extrusion of a semi-conductive polymer (ETFE) whose resistance varies with temperature. The

nnnn

characteristic is expoited to supply the required power in proportion to the process temperature and allows the cable to be overlapped without

nnnn

burning as the power reduces to almost zero as the polymer temperature limit is approached.

nnnn

Poorly insulated cable or cable that cross insulation or voids will not be affected by such use. However it is important to ensure that the pipe

nnnn

temperature does not exceed the maximum exposure temperature of the cable either when operating or switched off.

nnnn

Base (FEP jacket only)

nnnn

Reinforced (FEP jacket + tinned-copper braid)

nnnn

Anti-COrrOSion (FEP jacket + tinned-copper braid + fuoropolymer overjacket)

Exposure temperature (even when switched off): minimum -40 °C, maximum +215 °C. Minimum bending radius: 40 mm.

nnnn

Certifications (except for Base version): ATEX, FM, CSA, GOST for use in hazardous areas (EExe II T4/T3*).

nnnn

Parallel construction allows the cable to be cut on site and terminated and spliced by the installer.

nnnn

Circuit length up to 190 m long, depending on output, minimum temperature and type of circuit breaker.

nnnn

For quick calculation of cable length: pipe length + 10% for fittings, flanges, etc. Consider more if spirally wound.

nnnn

An electrical safety device must be installed

nnnn

according to the regulations.

nnnn

A thermal magnetic circuit breaker (curve C or

nnnn

K) with 30 mA differential control must be used

nnnn

for protection.

nnnn

Maximum voltage, out of hazardous areas: 277

nnnn

Standard versions for 110 V supply are

nnnn

available on request. Special versions for 24V

nnnn

or 48V (min. 1000 m).

nnnn

For selecting the

nnnn

calibration of the circuit

nnnn

breaker, use the table on

nnnn

the right, basing on the

nnnn

model, on the length of

nnnn

the installed cable and

nnnn

the minimum start-up

nnnn

temperature. The

nnnn

numbers in italic are the

nnnn

cable maximum length.
