This product is suitable for control circuits transmitting railway signals, audio signals, or automatic signal devices at rated voltages of AC 500V or DC 1000V and below. The composite sheathed and aluminum sheathed railway signal cables offer certain shielding properties, making them suitable for installation in electrified sections or other areas with strong electrical interference.

From a macro perspective, the entire Chinese wire and cable industry is experiencing rapid development and growth. Development is swift, and with it, issues arise. Particularly in the mid-to-low-end wire and cable product market, where technical value added is relatively low, price-cutting competition is quite prevalent. Industry insiders believe that the fundamental cause of the low-price competition is blind investment, overcapacity, and supply exceeding demand. On one hand, due to low investment thresholds, a large number of companies have flooded in, leading to an "overabundance" of enterprises within the industry.

Yangzhou PTYA23/Aluminum Sheathed Cable, 37x1.0, Conforms to Standard

2.1 The cable's operating environmental temperature is -40℃ to +60℃.

2.2 Cable conductor *The operating temperature should not exceed +70°C.

2.3 Cable Laying Environmental Temperature: Polyvinyl Chloride (PVC) coated cables should not be below 0℃; Polyethylene (PE) coated cables should not be below -20℃.

2.4 Allowable bending radius of cables: Non-armored cables should be not less than 10 times the outer diameter of the cable; armored cables should be not less than 15 times the outer diameter of the cable.

2.5 The ideal shielding coefficient for a comprehensive sheathed rail signal cable is ≤0.8; for an aluminum sheathed rail signal cable, it is ≤0.3.

*3* Delivery Length

Cables 500 meters and longer should account for at least 50% of the total delivery length; short cables between 50 to 250 meters in length should not exceed 5% of the total delivery length; the measurement error for cable length should not exceed ±0.5%. Delivery based on the agreed length as per mutual negotiation.

Up until the early 1990s, state-owned enterprises held an unshakable absolute dominance in our country's wire and cable industry. In the 1980s, the two dominant players were Shenyang Cable Works and Shanghai Cable Works; by the 1990s, a three-way tie was formed with Shenyang Cable Works, Shanghai Cable Works, and Zhengzhou Cable Works. 2. The manufacturing process involves a wide range of categories and a large material flow. The production of wire and cable encompasses a broad spectrum of manufacturing processes, from the smelting and pressure processing of non-ferrous metals to chemical technologies such as plastics, rubber, and paints;纺织 technologies like winding and weaving of fiber materials, to metal wrapping and metal strip longitudinal wrapping, as well as metal forming processes involving welding, etc.
