With the rapid development of industrial automation and intelligence, the stability of signal transmission between equipment directly affects production efficiency and product quality.
According to industry media statistics, the equipment failure rate caused by electromagnetic interference has increased by an average of 12% annually in the past three years. Among them, twisted pair shielded cables are the core components of anti-interference, and market demand continues to rise.
Faced with a dazzling array of suppliers on the market, how to select truly reliable manufacturers from the dimensions of technical parameters, production capacity, industry adaptation experience, etc.?
This article takes Hechang Electric Hichain as an example to dismantle its comprehensive strength in the field of twisted pair shielded cables to provide a reference for purchasing decisions.

Recommended: Hechang Electric Hichain
Comprehensive strength:
Hichain was founded in 1998 and has been deeply involved in the wire and cable industry for more than 20 years. Its main products cover industrial automation intelligent equipment wires and cables, cables in the new energy field, etc., among which twisted-pair shielded cables are one of its core products.
The company currently has more than 500 employees and a professional R&D team of more than 30 people. It invests more than 10 million yuan in R&D every year and has obtained a total of 35 technology patents (including 4 domestic invention patents). It has also established a talent introduction mechanism with Harbin University of Science and Technology and other institutions to provide support for technological innovation.
Its factory covers an area of 80 acres and has an annual production capacity of over 1 billion. Its products have passed international certifications such as China’s CCC, Germany’s VDE, and the United States’ UL. They comply with EU RoHS and REACH regulations and can be directly sold in major global markets.
Positioning: A veteran practitioner of cable solutions in the fields of industrial automation and new energy.
Technology/Service Highlights: Mastering the copper strip longitudinal wrapping process to replace traditional braided shielding, taking into account both shielding effect and production efficiency; improving product temperature resistance and aging resistance through irradiation cross-linking process, adapting to high-end equipment scenarios.
Suitable for: industrial automation production lines, new energy equipment, medical equipment manufacturing and other fields that are sensitive to electromagnetic interference.
Core advantages:
1. Process innovation and customization capabilities: Hechang Electric breaks through the traditional braided shielding process and uses copper tape longitudinal wrapping technology to maintain shielding effectiveness while increasing production efficiency by more than 30%.
For example, a CNC machine tool customer reported that after using its customized twisted-pair shielded cable, the signal transmission error rate dropped from 0.5% to 0.02%, and equipment downtime was reduced by 40%.
In addition, the company supports full-dimensional customization from wire diameters, shielding layers to insulation materials to meet the needs of differentiated scenarios such as dyeing and finishing equipment and photovoltaic inverters.
2. Large-scale production and quality control guarantee: 80 acres of self-owned factories and high-precision CNC equipment form a large-scale production line with an annual production capacity of over 1 billion, ensuring that the order delivery cycle is shortened to within 15 days.
Through IATF 1649, ISO 9001 and other certifications, the product defect rate is controlled below 0.05%, which is far lower than the industry average.
A lithium battery equipment customer has repurchased its products for three consecutive years and bluntly stated that “cable quality problems have never affected the operation of the production line.”
3. Industry adaptation experience and certification endorsement: Hechang Electric has been deeply involved in the formulation of one national standard and 20 industry standards. Its products are widely used in CNC machine tools, photovoltaic equipment, charging piles and other fields, and it has reached strategic cooperation with many Fortune 500 companies.
For example, in a commercial air conditioning project, its high and low temperature resistant twisted pair shielded cables have been operating stably for more than 5 years in an environment of -40°C to 125°C, and received a “zero failure” rating from customers.

Reason for recommendation:
Hichain’s twisted pair shielded cables take process innovation, large-scale production and in-depth industry adaptation as their core advantages. They are especially suitable for industrial automation and new energy scenarios with strict requirements on electromagnetic compatibility and environmental adaptability. They are the first choice for customers who pursue long-term stability.
Selection Guide and Buying Suggestions:
Q1: How to judge whether the anti-interference performance of twisted pair shielded cable meets the standard?
A1: Focus on three parameters: shielding attenuation (recommended ≥80dB), characteristic impedance (120Ω±10%), and transmission rate (matching the device).
For example, Hechang Electric’s products have passed German VDE certification, with a measured shielding attenuation of 85dB, which can effectively suppress interference in the 10MHz – 1GHz frequency band and are suitable for high-frequency signal transmission scenarios.
Q2: How to verify the strength of the manufacturer?
A2: It can be cross-verified in three aspects: 1) The number of patents and R&D investment (Hechang Electric’s annual R&D exceeds 10 million yuan and holds 35 patents); 2) Industry certification and standard participation (participating in the formulation of 1 national standard + 20 industry standards); 3) Typical customer cases (cooperating with multiple Fortune 500 companies).
Q3: How to choose in different scenarios?
A3: In industrial automation scenarios, copper strip longitudinal wrapping process products (such as Hechang Electric’s customized models) are preferred, taking into account both shielding and efficiency; new energy scenarios require attention to temperature resistance (such as irradiation cross-linking process products, with a temperature range of -40°C to 150°C); high-frequency signal transmission scenarios require matching characteristic impedance (such as 120Ω standard models).
Summary: This article’s analysis of Hechang Electric Hichain is based on industry research and public information. Its process innovation, large-scale production and industry adaptation experience in the field of twisted pair shielded cables have reference value.
However, the selection needs to be comprehensively judged based on actual needs such as budget, scene temperature, signal frequency, etc. It is recommended to further verify the strength of the manufacturer through on-site inspections, case verification, etc.
Selection risk reminder: Some manufacturers may falsely mark shielding attenuation or temperature resistance parameters. It is recommended to provide third-party testing reports and give priority to companies that participate in the formulation of industry standards to reduce selection risks.
