BBTRZ
This product is suitable for transmission of electric energy in power lines with a rated voltage of 0.6/1KV and below. It is difficult to catch fire and has the ability to prevent or delay the spread of flames. It is used for laying in a variety of occasions where cables have flame-retardant requirements, such as high-rise buildings, hotels, hospitals, subways, nuclear power plants, power plants, ore, petroleum, and chemical industries. Plastic fire-resistant cable, also known as isolated fire-resistant cable, is a layer of odorless, non-toxic, halogen-free mineral compound material between the insulated core (outer diameter of the cable) and the outer sheath of the cable. When the cable is subjected to a fire, a large amount of crystal water is formed by filling and chromatography. When the flame temperature is lowered, the hydroxide is dehydrated into an infusible and non-combustible inorganic hard shell, which blocks the oxygen supply channel and achieves a high level of fire resistance. .

Instructions for plastic fireproof cable
Plastic fire-resistant cable is also called isolated fire-resistant cable. It is filled with a layer of odorless, non-toxic, halogen-free mineral compound material between the insulated core (outer diameter of the cable) and the outer sheath of the cable. When the cable is subjected to a fire, a large amount of crystal water is formed by filling and chromatography. When the flame temperature is lowered, the hydroxide is dehydrated into an infusible and non-combustible inorganic hard shell, which blocks the oxygen supply channel and achieves a high level of fire resistance. .
Product structure
plastic fireproof cable is composed of copper stranded wire, cross-linked polyethylene insulation, mineral compound filling and wrapping, and low-smoke halogen-free sheath.
In addition to meeting the flame-retardant, low-smoke and halogen-free characteristics of low-smoke and halogen-free cables, plastic fire-resistant cables also meet the requirements of BS6387C, W, and Z laboratory standards.

a, the name or trademark of the manufacturer i
b, cable model and specification i
c, length im
d, manufacturing date year and month
e, standard number i
f, gross weight i kg.

Installation and laying
1. Installation: According to Clause 2.13.10.4 of JGJ16-2008 "Code for Electrical Design of Civil Buildings", BBTRZ cable pair shall be used for the fire-fighting line, and the laying protection measures of the line shall meet the fire-proof requirements
2. Laying:
2.1 The maximum span of the cable should meet the following requirements:
Allowable Span (mm) Allowable Span (mm)Cable outer diameter
Outside Diameter
Laying Type Horizontal Horizontal Vertical Vertical D≤20 400 1000 20 600 1200 30 800 1500 D＞50 1000 2500 Laying method
2 2 The cable tray meets the load-bearing capacity of the support and the outer layer of the lossless cable and its core.
2 3 The cable tray should enable the cables to be arranged neatly with each other.
2 4 Parts such as leather goods, cable ties, ropes or supporting parts for fixing cables shall have a smooth surface, easy installation, sufficient mechanical strength and durability suitable for the environment in which they are used.
25 The selection of cable fixing components should meet the following requirements:
Except in the case of AC single-phase power cables, anticorrosive flat steel clamps or nylon cable ties or plastic-plated metal cable ties can be used. Nylon cable ties or plastic-plated metal cable ties should be used in strong corrosive environments.
For the rigid fixing of AC single-phase power cables, aluminum alloys and other clamps that do not constitute a magnetic closed circuit should be used. For other fixing methods, nylon ties or ropes can be used. Do not tie the cables directly with iron wires.
