In a line system, it is impossible for operation and maintenance personnel to memorize all the devices and lines one by one. In order to avoid omissions during inspections, line identification management is essential. After marking each line, it should be sorted and summarized, and posted in a conspicuous position. When conducting inspections in the future, as long as the inspections are carried out in strict accordance with the project requirements, no omissions can be made.
Intelligent engineering cable label
First, the characteristics of cable identification
The cable identification system can not only provide correct guarantee for the operation and maintenance personnel to carry out correct daily maintenance and abnormal accident handling, but also provide help for future generations.
2. How to choose the cable label
Mark the terminal before or after it is done
Cable Identification Card:
1. Can be used before or after terminal connection
2. The content is clear. The label wraps completely around the cable.
Heat Shrinkable Cable Identification Tube:
1. It can only be used before the terminal is connected, and the open end of the wire is sleeved over the wire.
2. The logo can be changed at will before heat shrinking or socketing, with flexibility
3. After the terminal is connected, the sleeve becomes a permanent mark that can withstand harsh environments. and low cost.
What is the diameter of the cable
The diameter of the cable determines the type of marking, length or diameter of the sleeve required.
Cable identification cards are generally used on large square cables, large pairs of cables, and outdoor optical cables.
The heat shrinkable marking tube is generally used on the small square secondary small line. Identification cards are available for cables of various diameters.
3. What kind of environment will the cable label be placed in?
It is critical to choose an optimal cable identification. Factors to consider include:
1. Will it come into contact with oil, water, chemicals or solvents?
2. Do you need flame retardant?
3. Does the country have special regulations or other regulations for this?
4. Is it used in clean or other environments? Even in harsh environments, thermal transfer printing, industrial-grade printing quality, and strong anti-fouling, in fact, the printed content is also "oil-resistant".
Fourth, plan to print your own or buy pre-processed logos
To buy cable identification:
1. There are a variety of pre-printed content to choose from;
2. If the demand is relatively large, customized pre-printed content can be provided;
3. There are various markings such as identification card and sleeve type to choose from, which is convenient to use and transport;
4. Suitable for various applications.
Self-printing logo:
1. Print various content as needed (even if you print a small amount);
2. There are various label and sign sleeve materials for portable printers, thermal transfer printers, and computer-based printers;
3, suitable for printing longer characters;
4. There are label sizes suitable for different applications.
Five, cable identification requirements
The implementation of the wiring label identification system is to bring the greatest convenience to the user's future maintenance and management, improve their management level and work efficiency, and reduce network configuration time.
All facilities that need to be identified must have labels, and each cable, optical cable, wiring equipment, termination point, grounding device, laying pipeline and other components should be given a unique identifier. Identifiers should be marked with the same number of letters and numbers, and follow certain patterns and rules. It is recommended to select materials according to the concept of "permanent identification", and the life of the label should correspond to the design life of the wiring system. It is recommended that the label material comply with the UL969 (or corresponding standard) certification to achieve the guarantee of permanent identification; at the same time, it is recommended that the label should meet the requirements of the environmental protection RoHS directive. All labels shall remain legible, complete and meet the requirements of the environment. Labels should be printed, no manual filling is allowed, and should be clearly visible and easy to read.
It is particularly emphasized that the label should be able to withstand the test of the environment, such as humidity, high temperature, ultraviolet light, and should have the same or longer service life as the identified facility. Materials such as polyester, vinyl or polyolefin are usually the best choices. All management facilities are to be documented. Documents should be recorded and stored by computer. Simple and small-scale wiring projects can be managed according to paper documents such as drawings and data, and the records should be accurate, updated in time, easy to consult, and documents should be Chinese.
5.1 Indoor and outdoor use
Labels for indoor and outdoor use should be able to withstand environmental conditions, such as humidity, high temperature, UV light, and should have the same or longer service life as the identified facility. It is recommended that the label material comply with the UL969 (or corresponding standard) certification to achieve the guarantee of permanent identification; at the same time, it is recommended that the label should meet the requirements of the environmental protection RoHS directive.
5.2 Cable identification
The most commonly used cable identification is the cover film label, which is adhesive and has a transparent protective film outside the printed part to protect the label printing from abrasion. In addition, non-laminated labels, flag labels, and heat-shrinkable sleeve labels can also be used on a single cable/jumper. Common material types include: vinyl, polyester, and polyvinyl fluoride.
For bundled cables, it is recommended to use identification plates for identification. This kind of label can be printed by a printer, fixed with a nylon cable tie or a felt tape and bundled with the cable, and can be placed horizontally or vertically. The label itself should have good tear-proof performance and comply with the corresponding RoHS standards.
The most commonly used cable identification is the cover film label, which is adhesive and has a transparent protective film outside the printed part to protect the label printing from abrasion. In addition, single cable/jumper can also use non-laminated labels, flag labels, heat shrink sleeve labels, as shown.
5.3 Labeling of the wiring panel/outlet panel
The wiring panel markings are mainly flat markings, requiring materials that can withstand the test of the environment, comply with the environmental requirements corresponding to RoHS, maintain good image quality in various solvents, and can be pasted to materials including low surface energy plastics. various surfaces. Labels should be printed, no manual filling is allowed, and should be clearly visible and easy to read. All labels shall remain legible, complete and meet the requirements of the environment.
