Shanghai Panda Cable Co., Ltd., formerly known as Shanghai Plastic Wire Factory, was founded in 1947, famous for the production of "Panda" brand wire, is one of the oldest and most influential professional factories in China's electrical equipment wire and cable industry, and is a "time-honored brand" familiar to many old Shanghainese. In the field of home improvement cloth wires, Panda wire is a recognized leading brand in the industry.
 
The structure and process of cloth wires are simple, and the market access threshold is low, but there are still obvious differences in the advantages and disadvantages of materials used by manufacturers. According to the copper core analysis and testing report issued by the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences (formerly the Shanghai Institute of Metallurgy of the Chinese Academy of Sciences) on the Panda wire, the copper content of the copper material is 99.99%, and the quality of the materials is higher than that of most brands on the market. The copper purity of the conductor is the decisive factor for the resistance of the wire, and the lower the impurity content, the lower the resistivity, and the stronger the conductivity in the case of the same cross-sectional area. Panda Wire has strict quality supervision, and every year samples will be sent to Shanghai Cable Research Institute for product testing, and the testing agency is the most authoritative scientific research unit in China's cable industry.
 
In terms of production process, Panda Wire still uses traditional tank annealing to eliminate the internal stress of copper wire, so as to avoid the problem of uneven hardness at both ends caused by continuous tension and retreat. The appearance of the finished copper wire is bright, the copper core is soft, the copper material is not easy to oxidize, the attenuation curve of current carrying performance is gentle, and the copper core at the end of the wire will not be blackened if it is exposed for a long time. In terms of insulation, Panda wire is made of materials that comply with the EU RoHS environmental protection directive, and has good flame retardant characteristics.
 
Panda Wire has been involved in cable products in various fields, especially in the field of cloth wires. The specifications of BV hard wire (commonly used PVC insulated copper core wire) suitable for home decoration cover 0.5 square meters, 0.75 square meters, 1 square meter, 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters, 10 square meters, 16 square meters, etc., with sufficient wire diameter, excellent copper quality, suitable insulation thickness, low eccentricity, round and solid appearance, heavy cable, good conductivity and safety, which can be called the industry benchmark. 0.5 square, 0.75 square, 1 square specification BV wire is less produced by other brands, and the wire diameter is thinner, which is generally only suitable for the laying of lighting circuits. In addition, BV wire products also cover 35 square meters, 50 square meters, 70 square meters, 90 square meters, 120 square meters and other large wire diameter specifications, most of which have exceeded the scope of home use. In addition to the standard 100 m/lap specification of the conventional 0.5 to 16 square BV wire, Panda Wire also provides 500 m/lap products, which is suitable for bulk purchases. Corresponding to excellent quality is the high selling price, taking BV2.5 and BV4 as an example, the price of Panda wire is 300 yuan and 522 yuan respectively, which is almost twice that of other brands on the market, which discourages many consumers.
 
BVR wire is also one of the common varieties of cloth wire, and its conductor is made of multi-strand copper wire, so the finished wire is softer than BV wire, and the difficulty of pipe construction is lower, which is deeply loved by construction personnel. Panda's BVR line also has complete specifications, from 0.5 square to 35 square are sold, the price is slightly higher than the same brand BV line, taking BVR2.5 square and BVR4 party as an example, the price of Panda wire is 348 yuan and 562 yuan respectively.
 
Panda Wire also complements BV wire and BVR wire with a rich range of flame retardant products, namely ZR-BV/BVR and ZBN-BV. The so-called flame retardant wire refers to the ability of the wire to prevent or delay the occurrence or spread of flames, and its insulation is usually made of specific combustion performance materials. Panda's conventional flame retardant line basically covers 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters and other home decoration wire diameters, up to Class B flame retardant, which is the highest flame retardant grade of BV/BVR line, and is the leading quality among similar products on the market. ZBN-BV has increased fire resistance characteristics and is generally less widely used in home decoration. Panda's flame retardant wire is more expensive, and the price is generally 30 to 50 percentage points higher than that of conventional wire of the same diameter.
 
In addition to conventional flame retardant wires, in recent years, the ascendant halogen-free flame retardant wires have a neat lineup under Panda, divided into WDZB-BYJ and WDZBN-BYJ, both of which are insulated with halogen-free polyolefin materials, the corrosiveness of combustion products is low, and the smoke and dust generated during combustion are less. Similar to ZR-BV/BVR and ZBN-BV/BVR, WDZB-BYJ and WDZBN-BYJ are more expensive, and WDZBN-BYJ is also less used on a large scale in home improvement.
 
In addition, Panda's BVVB multi-core sheathed hard wire is also available in a variety of specifications, this kind of sheathed wire is suitable for use as an open wire line, the cable is thick and strong, and provides customized zero-cut short sections, which can meet the needs of indoor all-surface installation, and is also suitable for local surface-mounted air conditioning wires, lighting cables, etc. BVVB wire is not priced high in Panda's home improvement cable, with a three-core 4-squared line of about 18 yuan/meter, and a two-core 1.5 square and two-core 2.5 square meters of about 5 yuan/meter and 9 yuan/meter respectively.
 
It should be noted that as a famous brand in Shanghai, Panda wire has been sold by impersonation and adulteration many times, there are many counterfeit and shoddy products on the market, and the purchase needs to be carefully identified. Panda Wire has three flagship stores online: Tmall, Jingdong and Suning, and offline authorized distribution outlets can be found on the official website, mainly in East China.
