Company scope
What the company makes
Ningbo Qrunning Cable (宁波球冠电缆股份有限公司) is a cable manufacturer in Beilun, Ningbo. Its Chinese company page traces the business back to 1990, and its 2025 annual report carries the same legal name together with the English name Qrunning. Alongside its wider power and high-voltage range, the catalogue has a page just for photovoltaic cable, listing PV1-F and H1Z2Z2-K as separate designations. Everything below is drawn from that PV page and the related company documents.
PV1-F comes in single-core sections from 1.5 to 35 mm². H1Z2Z2-K runs from 1.5 up to 240 mm². Before you pick a section, check it against the wire range of your junction box and connector. The catalogue gives AC and DC voltage rows separately, and the DC figures apply between conductors, in an unearthed system, with no circuit load. Request Qrunning's complete voltage rating statement for your application. Temperature figures come in three kinds: ambient limits of −40 to 90°C, a normal conductor maximum of 120°C and a short-circuit limit of 200°C. Current-carrying capacity and connector pairing need separate data from Qrunning and your connector maker.
Qrunning publishes a laboratory page with CNAS number L23155, the test methods it runs and the limits on each method. The annual report describes how the lab was built up in 2025. For product approval, ask for the current certificate that names your designation and section, and for test results on terminated assemblies if you need them. The same report mentions a development project for flexible PV cable that resists rodents, ants and UV; ask whether a released grade exists before you specify those features.
The Chinese site links to an English export site, which is useful for checking contact details. Its solar and wind category also carries medium-voltage products and some text about pipes and fittings that belongs to another product line, so take PV cable data from the Chinese PV page. A good order starts with the exact designation, section and construction, then ties each delivered reel to your termination process and to the test documents you agreed.

The entries below cover selected products and series from this manufacturer. Ask for the full catalogue if your project needs other models.
H1Z2Z2-K PV cable component family →
H1Z2Z2-K is Qrunning's single-core solar cable in sections from 1.5 to 240 mm², rated 1.0/1.0 kV AC and 1.5 kV DC between conductors. It sits beside the smaller PV1-F range. Order it by section and construction, and validate it with the exact… [2]
Specifications & selection questions →Start from the PV page
Specify a PV cable designation, separate from Qrunning's high-voltage and wind range
Two PV designations
Section sizes and voltages differ between the two PV designations, PV1-F and H1Z2Z2-K. Write the exact designation and construction into your order, since a family photo covers many reels. [2]
Connector and box fit
Section alone leaves out outer diameter, strand build, insulation wall, crimp geometry and the connector seal range. Each terminated assembly needs its own approved cable, contact and process combination. [2]
Each method has a scope
Ask for the test plan behind the laboratory badge
| Test listed | Scope or limit on the page | What to request |
|---|---|---|
| Conductor DC resistance | Methods GB/T 3048.4 and GB/T 3956. | The result and method for your reel and section. |
| Insulation resistance | GB/T 3048.5, for sections up to 120 mm². | How Qrunning tests larger sections up to 240 mm². |
| Mechanical and ageing tests | Methods listed material by material. | Which test applies to which layer, and the scope of each. |
| PV product certification | The lab page lists methods; model certificates are separate documents. | The current EN 50618 certificate and annex for your configuration. |
Qrunning gives CNAS number L23155 and a May 2025 recognition date. Check the current registry entry and its scope when you approve the supplier. [3]
What the annual report adds
The 156-page 2025 report covers the lab build-up and PV cable development work. It describes the company; for a shipment, ask for the release report on your own reels. [5]
A traceable cable order
Link the cable reel to the way you terminate it
Fix the construction
Set designation, section, conductor material and class, strand build, diameter tolerance, colour and marking. Ask for controlled drawings and the full rating and certificate set. [2]
Make a termination sample
Use the real connector, contact and junction box. Agree strip length, crimp or joining instructions, tool identity, seal fit and assembly checks with every component supplier involved. [2]
Release reels against agreed tests
Record reel number, length tolerance, lot report, measured resistance and key dimensions. Keep Qrunning's approved sample and your termination test results filed with the order. [2][3]
Control later changes
Get lead time, packing and storage instructions and a change-notice clause. Stock, warranty, compound and producing site each belong in the contract, separate from the family name. [2][5]
Development work and temperature wording
Rodent-resistant PV cable is a 2025 project; ask before you specify it
A named development project
On page 24, the annual report records work in progress on a rodent-, ant- and UV-proof flexible solar cable. If you need those features, ask for the released grade name and its test package; the standard catalogue cable is listed without them. [5]
Three temperature figures
The Chinese page gives 120°C as the normal conductor maximum, −40 to 90°C as ambient and 200°C for short circuit. Ask which model, standard clause and duration each figure belongs to before you set operating limits. [2]
Project fit
Match the offering to your project
Cable buyers specifying exact PV reels and the leads made from them.
Module component teams matching cable to connectors and junction boxes.
Procurement teams that want reel-level test reports tied to each order.
Confirm before ordering
- Outer diameter, conductor construction and current-carrying data for the section you order.
- The current product certificate annex, a producing-site check and the approved termination combination.
- Which Qrunning entity signs export contracts.
Built from Qrunning's Chinese company, PV cable and laboratory pages, its English export category and the 2025 annual report.

Does Qrunning sell cable production lines?
No. Qrunning is a cable maker, and this listing covers its PV cable. [2]
Will a 240 mm² H1Z2Z2-K fit any connector?
240 mm² is the top of the H1Z2Z2-K section range. Every connector and box has its own wire, contact and seal range, so check yours against the cable's outer diameter. [2]
Does the CNAS lab cover product certification?
The lab's scope is set out method by method. Product certificates and shipment test reports are separate papers to request with the order. [3][5]
Is 120°C the ambient rating?
No. 120°C is the normal conductor maximum; the ambient range is −40 to 90°C. Have Qrunning state how each applies to your installation. [2]
