Cable types

Explosion-proof enclosures are characterized by strong metal enclosures with special close-fitting access covers and breathers that contain an ignition to the inside of the enclosure. Field wiring in the hazardous environment is enclosed in a metal conduit of the mineral-insulated-cable type. All conduit and cable connections or cable terminations are threaded and explosion-proof. Conduit seals are put into the conduit or cable system at locations defined by the National Electric Code (Article 501) to prevent gas and vapor leakage and to prevent flames from passing from one part of the conduit system to the other.

From Table 25.2, we saw that different cable types have different impedance characteristics and different transmission rates. Therefore, for the same fireset at the same charge voltage (and the same detonator), we should see different step amplitudes and step widths (and hence different burst points) for the same... 

Again, the current, as with the series arrangement, will be limited by the trunk cable. In this case, however, the current to each detonator in parallel will be the normal current divided by the number of detonators. The voltage will be the same as for normal firing. Thus a cable type and length that would have provided, say, a 700-A burst current for a single detonator, will provide only a 350-A burst for each of two detonators in parallel. This system also should be tested for the same parameters mentioned earlier before being fielded.

Each type of cabling has its own benefits and drawbacks. Table 8.2 details the most common types of cabling in use today. As you look at this table, pay particular attention to the cost, length, and maximum transmission rates of each cabling type. 

The electric heater installation employed to develop a combustion front consisted of the following component elements (a) a three-phase downhole heater, 3.3 m long and 116 mm in diameter, with rated power of 24 kg W (b) power cable, type KTNG-10 (c) control station, type TEH - 50 V/-13A3 (d) autotransformer ATS 3-30 (e) thennocouple, type HK and a thennal resistor for temperature control of air injected into bed and (f) a lubricator for sealing the wellhead.

For each compartment Ci the inventory matrix contains the plant specific code for each component j including the associated power supply and instrumentation and control (I C) cables inside the compartment. In a first step, the cable types have only been roughly classified (e.g. 22 cable classes for the reference NPP imder analysis) for a pessimistic estimate of the potential chcuit faiilts induced by fhe induced cable failures. In a second step, the Fhe PSA database has to be complemented by a database containing aU the cable data needed for performing a cable...

There are alternative cable types available with low-smoke, zero halogen (LSOH) characteristics, which are claimed to be safer and are being used in several nnderground railway systems in Europe and USA. 

Please also note, however, that CPL 02-01-034 lists several acceptable alternatives to control lines that are not horizontal cable-type devices affixed to vertical support members. These include a perimeter wall, guardrail system, or even a restraint system rigged so that non-leading edge workers cannot access the area.
