LSZH Supply Is Tightening – And Prices Are Already Moving Up

Question 1: What Are the Technical Differences Between LSZH and PVC Cables?

Simply put, LSZH (Low Smoke Zero Halogen) is a cable jacket material. The key difference between LSZH and conventional PVC cables lies in "what happens when they burn" — not in "whether they burn."

One sentence for buyers to remember: LSZH cables do not release dense smoke or corrosive gases in a fire. In environments like data centers — where both people and equipment are high-value — this difference can be critical.

Question 2: How Do LSZH Compliance Requirements Affect Projects Outside Europe?

In the short term: Only the EU‘s CPR (Construction Products Regulation) makes LSZH mandatory. But in the medium term, this standard is becoming the "de facto standard" for data center projects globally.

Three reasons why:

1. Multinational enterprises use one global standard. Google, Amazon, and Microsoft building data centers in Asia do not lower their safety standards just because the project is outside Europe. Their global procurement manuals specify the same specifications everywhere.

2. Insurers are driving the shift. Data center fire losses routinely run into the tens of millions of dollars. Major global insurers are increasingly incorporating "whether LSZH cables are used" into their premium assessment frameworks. Without LSZH, premiums are higher — and in some cases, coverage may be denied.

3. China is following suit. China‘s GB 50016 building fire code already requires LSZH cables in densely occupied spaces. While data centers are not yet separately listed as a mandatory category, the trajectory is clear.

One sentence for buyers to remember: Even if your project is not in Europe, LSZH is becoming the "unwritten rule" for global data center procurement. Not understanding it now means playing catch-up later.

Question 3: How Should Buyers Evaluate the Cost Structure and Value of LSZH Cables?

This is the question buyers care about most. Here is a direct answer.

Initial Procurement Cost

LSZH cables typically cost 30%–50% more than PVC cables of the same specification.

This is a fact. The reasons are straightforward:

●    Halogen-free materials are inherently more expensive than PVC

●    LSZH cable production requires dedicated production lines (to prevent PVC contamination)

●    CPR certification itself carries significant costs

But the Cost Story Doesn‘t End at the Purchase Price

The decision logic for data center cable procurement is: total cost of ownership > initial purchase price.

Cable costs typically account for less than 5% of total data center construction costs. But if a fire occurs, the losses can be catastrophic:

One sentence for buyers to remember: LSZH is not about "spending more money" — it is about "buying insurance." In a data center environment, saving tens of thousands on cables could mean losing tens of millions in a fire.

Smart Procurement: Tiered Specification

Not every area requires the highest grade. Industry best practice is tiered specification:
