Shanghai Qifan Cable is one of the largest manufacturers in the wire and cable industry, and its home improvement cable has strong competitiveness in Shanghai and surrounding provinces and cities, and its product popularity is second only to Panda Wire and Far East Cable.
 
The core of the canvas wire is made of 99.45% oxygen-free pure copper, which meets the requirements of the national standard and has a stable current-carrying capacity, but there is still a certain gap compared with the top brands. PVC insulation has low eccentricity and reliable insulation performance. The finished cable material has a good texture, the core is square, and the winding is beautiful.
 
The specifications of the sailing BV/BVR wire range from 0.75 square to 120 square meters, and it is generally recommended to use 1.5 to 10 square wires for home improvement wires. It is worth mentioning that the sail BV line is divided into single-strand and multi-strand wire below 1 square, the core structure of multi-strand BV line is similar to BVR, and the nominal second-class conductor is not recommended for home improvement concealment engineering due to the small wire diameter and limited current-carrying capacity, and is more suitable for the connection and fixed laying of electrical equipment. The price of BV1.5 square is about 100 yuan/circle, and the price of BV2.5 square is 166 yuan/circle.
 
There are two kinds of flame retardant lines for sailing, one is the conventional flame retardant BV line ZB-BV, the flame retardant grade is up to grade B, the flame retardant performance is good, and the purity of the wire core is slightly better than that of the general BV line; The other is polyolefin WDZB-BYJ wire, the insulation is cross-linked, the material strength is better, the composition is halogen-free, and the corrosive combustion products and the amount of smoke produced are lower. ZB-BV has the highest price among all kinds of products, ZB-BV2.5 square price is 208 yuan/circle, and the price of WDZB-BYJ is basically similar to ZB-BV.
