BTTZ mineral insulated cable how separation? more core installation of Micc cable
What mineral insulation cable USES is copper tube copper sheath is so when producing, cannot divide yellow green red color like electric wire so, need to measure first before construction.

1.how does mineral insulation cable separate color?

General production of mineral insulation cable manufacturers will not color, only provide the longest number of meters of cable into coil delivery, are divided by the construction party themselves construction installation. However, when pre-branching mineral insulated cable is made, the branching line will be made a color separation. Here are the specific steps:
a.First, use the meter to measure which two cables are connected at both ends.
b.and then the two ends of the same kind of heat shrink sleeve.
c.Fix the heat-shrinkable sleeve with the blowtorch.

2.Key points for construction of BTTZ mineral insulated cable terminal head:

a.the construction site to choose a dry environment for installation, it is best not to construction in rainy days, because the BTTZ terminal head is susceptible to moisture.
b.The construction of BTTZ cable terminal head and intermediate connector must use qualified silica gel, sealant and special tools to remove powder debris. When using sealant or silica gel, no debris shall be mixed in, so as not to affect the sealing effect.
c.the cable hardness is relatively large, if the cable bending is serious, can use special pipe bender to correct it to make it smooth and uniform transition, avoid crossing and overlap. Do not use ordinary tools or manual bending, so as not to damage the cable copper sheath in operation. The position of terminal head and intermediate joint should be calculated accurately. Select the position that is easy for inspectors to check.
d.in the construction process, should not be arbitrarily divided. Only when the attachment is installed can it be cut off, and once the cable is separated, the terminal and connector must be installed immediately.
Five factors, the cable structure rigidity is hard, in order to eliminate BTTZ heat bilges cold shrink cable (force) to produce craze, access to the "S" type or "Ω" type connector.
Note that the insulation resistance should be measured again to reach 100 megohm or more before sealing, and the mineral cable should be kept energized after installation, so that water molecules can hardly enter the insulation body. Many fire protection systems do not work for a long time, which will lead to the failure of fire protection performance over time. BTTZ can also be directly buried in water, and the life of the long electrified state is also very long.
