What are the main factors that influence cable price fluctuations?

Cable raw materials account for over 70% of production costs, and price fluctuations result from multiple interacting factors, primarily falling into the following six categories:

I.Non-ferrous metal raw materials (primary influencing factor, accounting for the largest share):

1.Copper price (main material for low-voltage power cables and home electrical wiring)：

Copper serves as the core conductor in the vast majority of copper-core cables, with its raw material cost constituting 60%-75% of the total cable price. Spot and futures prices for Shanghai copper and London LME copper fluctuate daily in real time; daily price movements directly reflect changes in cable ex-factory prices. Rising copper prices lead to upward adjustments in cable prices on the same day or the following day, while sharp declines result in price reductions.

2.Aluminum prices (for aluminum-core cables, overhead lines, and aluminum alloy cables):

The costs of aluminum-core cables, YJLVs, and insulated overhead lines are closely tied to electrolytic aluminum prices, and fluctuations in aluminum prices directly impact the pricing of aluminum-based cables.

3.Auxiliary materials such as tin and zinc:

Tin-plated control cables and armored cables require tin or galvanized steel strips; increases in tin prices and steel costs will slightly raise the production cost of specialized cables.

II. Raw Materials for Rubber and Plastic Chemicals (Materials for Insulation and Sheathing)

The cable insulation layer and outer sheath are manufactured from chemical materials such as PVC, PE, cross-linked polyethylene, and low-smoke, halogen-free compounds.

1.Fluctuations in crude oil prices directly impact the prices of plastic particles and PVC resin raw materials; rising international oil prices lead to increased costs for rubber and plastic raw materials, consequently raising cable production costs as well.

2.Flame retardants, fire-resistant powders, and fillers are subject to fluctuations in chemical production capacity and raw material supply-demand dynamics; consequently, flame-retardant, fire-resistant, or low-smoke halogen-free cables exhibit more pronounced price volatility compared to conventional YJV cables.

III. Market Supply-Demand Dynamics and Industry Production Cycle   

1. Price fluctuations during peak and off-seasons: From March to June and September to November each year mark the peak periods for infrastructure projects, real estate developments, and factory upgrades, leading to surging cable demand, full production orders, tight supply, and price increases; whereas the shutdowns during the Spring Festival in January-February and high-temperature periods in July-August constitute traditional off-seasons with declining demand, prompting manufacturers to lower prices to boost sales volume.

2.Changes in production capacity supply and demand: During periods of overcapacity in the cable industry, manufacturers compete by offering low prices to secure orders; environmental production restrictions and maintenance shutdowns at major plants lead to reduced capacity, resulting in spot shortages and price increases.

IV. Environmental Protection, Energy Consumption, and Industrial Policies   

1.Production Restrictions Due to Environmental Regulations: Chemical plants, copper smelters, and rubber/plastic processing facilities have suspended operations or reduced production following environmental inspections; this has led to tightened supply and price increases for raw materials, which are subsequently passed on to end-users of cables.   

2.Dual Control of Electricity Prices and Energy Consumption: Copper and aluminum smelting are energy-intensive industries; the increase in industrial electricity prices has raised production costs and driven up prices of metal raw materials.   

3.New national standard regulations:Upgraded national standards (increased conductor and insulation thickness requirements) have led to higher material usage and consequently increased production costs for cables of the same specification.

V. Transportation Costs, Fuel Expenses, and Labor Costs   

1.Rising prices of refined oil products lead to increased vehicle logistics costs and higher additional expenses for long-distance shipments;   

2. Rising labor wages in the manufacturing sector and increased utility costs (water and electricity) slightly impact the unit price of cables;   

3. Provincial transportation restrictions and adjustments to highway toll rates also marginally affect short-distance delivery costs.

VI. Customization and Product Specific Characteristics (Price Differences Between Models with Similar Specifications)

1.Additional Costs for Special Properties:Flame-retardant ZR, fire-resistant NH, low-smoke halogen-free WDZ, armored YJV22, and corrosion-resistant specialty cables require special additives, resulting in significantly higher costs than standard cables;

2.Custom Specifications:Non-standard core counts, non-standard voltages, custom printing, or short-meter orders incur higher production costs and lead to higher unit prices compared to regular stock products;

3.Procurement Volume:Large-scale bulk purchases offer lower unit prices, whereas small-scale individual orders carry higher unit costs.

VII. The Macro International Environment

International commodity prices, the US dollar exchange rate, import-export trade policies, global mineral production capacity (particularly in copper and aluminum mining), and geopolitical conflicts all indirectly affect international copper and aluminum futures, thereby driving fluctuations in domestic raw material and cable prices at their source.

VIII. Procurement Recommendations:

For large orders, closely monitor the Shanghai copper futures market and build up inventory in bulk when prices are low; for short-term urgent needs, purchase small quantities as required to avoid increased procurement costs due to sharp price rises of raw materials.
