Ⅰ. Characteristics and application
It is stranded with a certain number of twisted extension wire pairs or shield extension wire pairs, covered with shield layers, sheathed and armoured layers. The type, specification, class and structure sizes of extension wire pairs are generally same. When a special requirement is given, the cable can also be formed by different extension wire pairs.
There are many kinds of shield for twisted extension wire pairs such as copper wire or tin plated copper wire braid shield, composite aluminium-plastic tapes wrap shield, composite copper-plastic tape wrapped shield, copper tapes shield, “general shield” and “sub plus general shield ”. It is possible to select the shield according to requirements of interference prevention.
Extension Cable is used to extend cold clamps of thermocouple and connects them with instruments, which forms temperature-testing system.
Extension Cable used in thermocouple for intrinsically safe explosion-proof temperature testing system consists of multiple-pairs of extension wire. In that case, the characteristics of the cable are just the same as those of the wire used for intrinsically safe explosion-proof temperature testing system.
Intrinsically safe extension cable extends cold clamps of explosion-proof thermocouple for a certain distance to connect instruments, which forms intrinsically safe explosion-proof temperature-testing system.
