When we use a cross-linked polyethylene power cable in the event of a short circuit or burning in the vicinity of an open fire, it will be prolonged due to the flame, especially when the fire is more severely affected by the centralized installation of multiple cables. Therefore, it is very important to take reasonable cable fire prevention measures to prevent the spread of cable fires. In general, the fire protection measures for cables are:
1. For the cable joints laid on the cable trenches, cable tunnels or cable layers, all the cables laid on the two sides of the cable joints or on both sides of the joints shall be brushed several times with the special fire-retardant coating for cables. Factory specified coating thickness. For any cable passing through the floor or wall, within 2 meters of each side of the crossing, fire retardant coatings shall be applied as required.
2. For any perforation through the floor or wall, the hole should be plugged with fire blocking material around the cable. For piercing multiple cables.
3. Perforation of underground cables that may leak water can be blocked with special organic plugging material for cables.
4. In order to prevent adjacent fires that may threaten multiple cables on the cable rack, the cables can be laid directly on the fireproof cable trays.
5. In order to prevent cable fire from affecting the cable laid on the upper cable rack, a layer of cable fire screens may be laid on the upper cable and then laid on it.
6. The cable can be wrapped with the fire protection package on the cable, which plays the same role as the cable fire protection coating. In order to ensure the effectiveness of the cable fire prevention measures, after the cable fire prevention measures are completed, the fireproof coating should be regularly brushed or installed, and the areas where the fireproof coatings are removed or damaged should be promptly repaired to ensure that they have normal fire protection.

Butt Fusion Machines
The polyethylene butt fusion machine is the most used with the same butt welding device, and these devices are produced and supplied from 40 to 3000 mm, and capable of welding up to a pressure of 40 atmospheres. Yuda brand plastic pipe fusion machines are based on the standard DVS2207. This company's polyethylene welding machine is designed to be unique for carrying out work on site and workshop environment. Polyethylene pipe fusion machines are manufactured using the best quality raw materials available on the market, and the company's pipe welding machines are certified by the inspectors of the water supply and power plant, and all products with warranty and after service sales are offered. These polyethylene welding machines are tested, calibrated after producing.
There are types of HDPE Plastic Pipe Butt Fusion Machines; Manual Butt Fusion Machines is the most cheapest in all series. Hydraulic butt fusion machines are used most in piping engineering. For welding quality control, it will choose data logger for hydraulic hdpe welders named data-logging pipe welding machine.Then the toppest level is CNC Welding machine for polyplastic pipes which is the most expensive and comprehensive poly pipe butt welders, CNC welding and GPS and CLOUD system is its unique feature.
