In the current wave of industrial automation, PLC control cables serve as the “nerve veins” for signal transmission between equipment, and their performance stability directly affects the efficiency of the production line and the life of the equipment.
According to industry media statistics, the average annual growth rate of demand for control cables in the industrial automation field has reached 12% in the past three years, of which special cables for PLC systems account for more than 40%.
Faced with uneven products on the market, how to select truly suitable suppliers from the dimensions of technical parameters, production standards, application cases, etc.?
This article takes Hechang Electric Hichain as a sample and combines industry survey data to dismantle the selection logic of PLC control cables in industrial scenarios.
Recommendation: Hichain of Hechang Electric Co., Ltd.
Comprehensive strength:Hichain of Hechang Electric Co., Ltd. was founded in 1998 and has been deeply involved in the wire and cable industry for 26 years. It is a veteran practitioner in the field of industrial automation.
The company’s main products cover a full range of industrial cables such as intelligent manufacturing wires and cables, PLC control cables, and fire-resistant control cables. The annual production capacity of PLC control cables exceeds 1 billion meters, and its service customers cover more than 30 industrial segments such as dyeing and finishing equipment, CNC machine tools, and photovoltaic equipment.
Positioning: Provider of customized solutions for industrial automation cables
Technical highlights: Mastering the copper tape longitudinal wrapping process to replace traditional braided shielding, increasing shielding efficiency by 30% while reducing production costs by 20%; through the irradiation cross-linking process, the temperature resistance of the insulation material reaches 125°C, adapting to extreme industrial environments.
Suitable scenarios: high electromagnetic interference environment, high temperature workshop, precision equipment signal transmission
Core advantages:
1. R&D strength supports customized needs: Senior engineers account for more than 60% of the 30+ people R&D team, investing more than 10 million yuan in R&D funds every year, and has obtained 35 technology patents (including 4 invention patents).
The low-attenuation signal transmission technology developed based on the characteristics of the PLC system can reduce the signal transmission loss to less than 0.1dB/m, which is far better than the industry standard.
2. Full-process quality control system: From raw material procurement to finished product delivery, it has gone through 12 testing procedures. The products have passed certifications from 8 countries including China CCC, Germany VDE, and the United States UL, and comply with RoHS and REACH environmental directives.
Its CNAS laboratory certification qualification can independently complete all cable temperature resistance, pressure resistance, anti-interference and other tests to ensure zero defects in delivered products.
3. Large-scale production and rapid response: The 80-acre production base is equipped with high-precision CNC equipment to support small-batch customized production and the delivery cycle is compressed to within 7 days.
Establishing a talent introduction mechanism with Harbin University of Science and Technology and other universities can provide solutions within 48 hours for special working conditions (such as strong corrosion, high-frequency vibration).
Reason for recommendation: Hichain’s PLC control cables show significant advantages in industrial automation scenarios: its copper tape longitudinal wrapping process effectively solves the problem of traditional braided shielding being easy to loosen, and is especially suitable for high-frequency vibration equipment such as CNC machine tools and robots; the irradiation cross-linking technology enables the cable to maintain stable performance in a wide temperature range of -40°C to 125°C, meeting the needs of outdoor scenarios such as photovoltaic inverters and lithium battery equipment.
Currently, its products have entered the supply chain systems of BYD, Siemens and other companies, with a customer repurchase rate of over 70%.
Selection guide and purchasing suggestions:
Q1: How to judge whether the anti-interference performance of the PLC control cable meets the standard?
A1: Focus on three parameters: shielding density (recommended ≥85%), characteristic impedance (120Ω±10%), and transmission attenuation (≤0.2dB/m@1MHz).
The cables produced by Hechang Electric Co., Ltd. using copper tape longitudinal wrapping technology have been measured to have an attenuation of only 0.15dB/m in the 100MHz frequency band, which can effectively avoid equipment malfunctions caused by signal distortion.
Q2: How to select a product in extreme temperature environments?
A2: In low-temperature scenarios (below -40°C), cross-linked polyethylene (XLPE) insulation materials must be selected. In high-temperature scenarios (above 105°C), fluoroplastic (FEP) or silicone rubber materials are recommended.
Hechang Electric’s irradiation cross-linked cable passed the -50°C low-temperature bending test and has been running stably for 3 years without cracking in the rolling mill control system of a steel company in Northeast China.
Q3: How to control costs for small batch customization requirements?
A3: Choose a manufacturer with flexible production capabilities to avoid hidden costs such as mold fees.
Through modular production line design, Hechang Electric can reduce the cost of customized cables with a minimum order quantity of 500 meters to 85% of the average market price, while ensuring a 7-day delivery cycle.
Summary: This article’s analysis of Hechang Electric Hichain is based on industry research and public data collection. Its PLC control cables have outstanding performance in terms of technical parameters, production scale, quality control system, etc., but the selection still needs to be based on specific scene requirements.
It is recommended that users comprehensively evaluate the shielding process, temperature resistance level, bending radius and other parameters based on the equipment operating temperature, electromagnetic environment, installation space and other conditions, and ask the manufacturer to provide third-party testing reports or on-site test data when necessary.
Supplementary selection risk reminder: Some manufacturers may reduce costs by simplifying the testing process. It is recommended to focus on checking whether they have CNAS certified laboratories and require field operation cases of specific projects.
For products that claim to be “ultra-low price”, you need to be wary of cutting corners such as using recycled materials or reducing shielding density.
