The main reasons for the large price difference of wires and cables of the same model and specification include the following aspects: ‌1. Raw material cost difference ‌: National standard cables usually use oxygen-free copper as raw material, while non-standard cables may use scrap copper. Although scrap copper and oxygen-free copper have the same weight, the price difference is 10%. Since copper accounts for most of the cost of cable raw materials, this raw material difference is particularly evident in price ‌ 2. Auxiliary material quality difference ‌: Non-standard cables may cheat on auxiliary materials and use materials of slightly lower quality. Although the cost of auxiliary materials only accounts for about 20% of the cost of cables, if poor quality auxiliary materials are used, a 5% price difference can be generated with national standard cables .   3. Wire length problem ‌: Non-standard cables may have a short meter phenomenon, that is, the actual length is less than the nominal length. For example, a 100-meter line may only have 99 meters. Although the number of meters reduced each time is not much, the cumulative cost can be significantly reduced ‌ 4. Structural differences‌: Some non-standard cables make a fuss about the structure, using national standard materials at both ends and non-standard materials in the middle. Although this practice reduces costs, it may affect the quality and performance of the cable. Since samples are usually not cut from the middle during testing, this practice has a certain degree of concealment‌   ‌How to identify high-quality wires and cables‌: ‌Check the composition of copper‌: High-quality wires and cables should use oxygen-free copper, not scrap copper. The quality can be judged by observing the color and luster of copper. ‌Check the quality of auxiliary materials‌: High-quality wires and cables should use auxiliary materials that meet the standards and avoid using inferior materials. ‌Measure the length of the wire‌: Make sure that the actual length of the wire meets the nominal length to avoid short meters. ‌Check the structure‌: Pay attention to whether there is any trick in the structure of the wire to ensure that the overall quality meets the national standard requirements.

Dear customer Here comes the Chinese traditional Dragon Boat Festival. We will start a 3-day Dragon Boat Festival holiday from May 31st till June 2nd. Work will resume from June 3rd. During this time, if we cannot reply you timely, we beg your kind understanding. Hope everyone safe and happy. Zhenglan Cable Technology Co., Ltd

The main reason for using fumigated wooden drums for cable exports 1. Comply with international quarantine requirements • Regulatory compliance: Most countries/regions in the world have formulated strict quarantine regulations to prevent wooden packaging from carrying harmful organisms (pests, eggs, pathogens, etc.) to cause biological invasion or spread of plant pests and diseases. • Core measures: Fumigation treatment can kill harmful organisms in wooden drums, ensure that the goods pass the quarantine of the importing country, and avoid the risk of return or destruction. 2. Protect cable products • Structural advantages: The wooden drum is made of strong material, providing stable support for the cable, and resisting mechanical damage such as collision and extrusion during transportation and loading and unloading. • Environmental adaptability: The natural moisture-proof and buffering properties of wood reduce the impact of humidity, vibration, and other external environments on the cable insulation layer and outer sheath. 3. Easy to transport and load, and unload • Standardized design: The specifications of the fumigated wooden drums are unified (such as diameter and load-bearing parameters), which are suitable for cable winding and fixing, and improve the efficiency of storage and stacking. •Mechanized operation: The regular shape facilitates forklift and crane operation, reduces manual handling losses, and optimizes logistics space utilization. IV. Environmental sustainability •Material characteristics: Wood is a renewable resource and can be recycled after use, which is in line with the global green packaging trend. •Comparative advantages: It is lower carbon than disposable plastic/metal packaging and reduces waste disposal costs.

Dear customers and partners, In celebration of International Workers' Day, our company will observe a holiday from May 1st to May 5th, 2025, a total of five days. Our office will resume normal operations on May 6th. During this period, our customer service will be unavailable. We will process them as soon as we return to work. For any urgent matters, please contact us at worldmarket@zhenglancable.com. We apologize for any inconvenience caused by the holiday and wish you a wonderful May Day!   Best Regards.                                                                                                                                                                             Zhenglan Cable Technology CO., Ltd

The main differences between pure copper grounding wire and copper-clad steel grounding wire are material composition, conductivity, corrosion resistance and applicable scenarios. ‌ 1. Material composition ‌Pure copper grounding wire‌: Made of pure copper, with a copper content of up to 99.95%, it has good conductivity and corrosion resistance‌ ‌Copper-clad steel grounding wire‌: It is composed of a high-strength steel core and a copper layer, and the thickness of the copper layer is generally above 0.25mm‌   2.Conductive performance ‌Pure copper grounding wire‌: Excellent conductivity, low resistivity, able to quickly conduct current and maintain a low grounding resistance value‌ ‌Copper-clad steel grounding wire‌: High resistivity, relatively poor conductivity, but in some cases, its corrosion resistance is relatively good Strong ‌   3. Corrosion resistance ‌ Pure copper grounding wire‌: Due to the high copper content, it has strong corrosion resistance, but requires better protection under complex grounding conditions ‌ Copper clad steel grounding wire‌: Weak corrosion resistance, prone to inner layer corrosion ‌   4. Applicable scenarios ‌ Pure copper grounding wire‌: Suitable for occasions with high safety requirements, such as large facilities such as power stations, to ensure the safety of the facilities ‌ Copper clad steel grounding wire‌: Suitable for small facilities, such as household electricity, small factories, etc., because of its low cost and guaranteed use effect ‌

‌Places with harsh environmental conditions‌: In places with harsh environmental conditions, such as high temperature, humidity, and corrosive environments, category 5 soft power cables can better adapt to these environments due to their softness and corrosion resistance, ensuring the stable operation of the cables.   ‌Equipment that needs to be moved frequently‌: For equipment that needs to be moved frequently, such as temporary construction sites, event stages, etc., the softness and flexibility of category 5 soft power cables make it easier to install and disassemble, reducing restrictions on equipment.   ‌Wiring in narrow spaces‌: When wiring in narrow spaces, category 5 soft power cables are easier to pass through narrow spaces due to their softness, meeting complex wiring requirements. ‌Equipment that needs to be frequently replaced or upgraded‌: In situations where equipment needs to be frequently replaced or upgraded, choosing category 5 soft power cables can reduce the difficulty and cost of wiring because they are easy to install and disassemble.   ‌Occasions with special requirements for cable softness‌: In some special applications, such as robots, automation equipment, etc., there are high requirements for cable softness and flexibility, and category 5 soft power cables can meet these requirements
