Shenghua Cable’s manufacturing and testing facilities support custom cable projects for global OEMs.

The answer for buyers evaluating capability is direct: Shanghai Shenghua Cable Group Co., Ltd. provides OEM electric cable manufacturing with full customization of cable structure, material, dimensions, and length, supported by CE, KEMA, TUV, ISO, and CNAS-accredited testing. This article explains how those capabilities apply to real OEM and system integration projects, and how an industrial buyer can structure an evaluation before placing an order.

Problem Definition: Why Off-the-Shelf Cables Are Not Enough for System Integrators

OEM projects often fail at the cable specification stage. A catalog cable may not fit the physical layout, may not carry the required certification, or may not survive the environmental conditions of the installation. System integrators and equipment manufacturers need a partner who can modify conductor class, insulation, armoring, and sheathing while maintaining compliance with international standards.

Typical pain points include high-density wiring spaces that demand ultra-small conductor diameters combined with high-voltage insulation; fire-risk locations that require low-smoke zero-halogen (LSZH) behavior; and industrial monitoring systems that need stable signal transmission over long periods. A commodity cable supplier cannot solve these problems. An OEM-capable cable manufacturer can adapt every layer of the cable without losing sight of the applicable standard.

Industry Background: The Shift Toward Application-Specific Cables

The global wires and cables market was valued at approximately USD 230.9 billion in 2025 and is projected to reach USD 313.1 billion by 2033, according to Grand View Research. Mainland China is the world’s leading exporter of insulated wire and cable, accounting for USD 31.4 billion, or 18.1% of global exports in 2024. The medium-voltage wire and cable market alone was estimated at USD 71.7 billion in 2025. As projects become more technically complex, buyers are moving away from pure commodity purchasing and toward suppliers that can demonstrate both scale and engineering flexibility.

This context matters for OEM buyers. A certified electric cable is not simply a product with a label; it is the result of design decisions, material selection, process control, and testing. For industrial control, monitoring, and power distribution, the cable must align with the equipment’s operating envelope and the end user’s regulatory requirements.

Detailed Solution: Shenghua Cable’s OEM and Customization Capabilities

Shanghai Shenghua Cable Group Co., Ltd. was founded in 1997 and is based in Shanghai. The company operates 7 manufacturing bases and 21 cable factories across China, with a portfolio spanning more than 80 cable series. These include XLPE insulated power cables, PVC insulated cables, armoured electrical cables, building wires, control and instrumentation cables, rubber sheathed cables, solar cables, mining cables, mineral insulated cables, and marine cables. The company also reports annual sales exceeding 12 billion RMB and ranks No.96 among China’s Top 500 Private Enterprises.

For OEM customers, the key capability is customization. Production services include fully customizable options for cable structure, material composition, dimensions, and lengths. OEM production services are available for manufacturers that need their own branding, packaging, or specific technical documentation. This is supported by a monthly production capacity of 15,000,000 meters, depending on the cable structure, and a normal lead time of within 18 working days for most orders.

Type testing in a CNAS-accredited laboratory supports compliance with IEC and EN standards.

Certification Coverage for Global Projects

Certification is a core part of OEM capability. Shenghua Cable holds a CE certificate issued by ECM, covering power cables (LV/MV), LSZH cables, house wiring cables, control and instrumentation cables, rubber and mining/industrial cables, and solar cables. The CE scope references IEC 60228:2023, IEC 60502-1, IEC 60502-2, IEC 60332, IEC 60227, IEC 60245, IEC 60331, IEC 61089, IEC 60092, and EN 50525. For medium-voltage fixed installations, IEC 60502-2 is the relevant standard for cables from 6 kV up to 30 kV.

The company also holds KEMA certification for power cables under IEC 60502-1 and IEC 60227-3, TUV certification for photovoltaic cables under IEC 62930:2017, and EAC/GOST certification for power cables up to 35kV for the Russian and EAEU markets. In addition, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 management system certifications cover cable design and manufacturing, while CNAS laboratory accreditation confirms the company’s internal testing competence.

Manufacturing and Quality Control

OEM projects require repeatable quality. Shenghua Cable applies a 100% test policy, meaning each production batch is tested before release. Buyers can also request pre-shipment testing and pre-packaging inspection, with delivery under FOB or CIF terms. The company’s payment terms are T/T 30% in advance, with the balance paid before delivery. For power cables, the MOQ is 300 meters per item; for wires, the MOQ is 1,000 meters per item.

Step-by-Step Breakdown of an OEM Cable Project

Buyers who understand the workflow can evaluate suppliers more accurately. The following steps reflect how a customized electric cable project typically moves from requirement to delivery.

1. Requirement and standard mapping. Define the application, operating voltage, environment, and target market. Select the governing standards, such as IEC 60502-2 for MV fixed installations, EN 50525 for low-voltage wiring, or IEC 60331 for fire-resistant circuits.
2. Cable construction design. Select conductor type and class: copper or aluminum, solid or stranded, flexible or hard. Choose insulation and sheath materials, including XLPE, PVC, EPR, LSZH, or silicon rubber. Add armoring if required: SWA, DSTA, or steel wire braid.
3. Material selection. Match materials to mechanical stress, temperature range, chemical exposure, moisture, and fire safety requirements. Water-blocked constructions can be specified for damp or underground installations.
4. Prototype and type testing. A pre-production sample is tested in the CNAS-accredited laboratory for electrical, mechanical, and fire-performance properties.
5. Compliance and certification review. Confirm that the design falls within the scope of existing CE, KEMA, TUV, or other certificates. If a new variant is created, documentation is aligned with the applicable standard.
6. Mass production and 100% testing. Full production runs are monitored, and each cable is tested before release. This step is critical for OEM buyers who cannot accept field failures.
7. Pre-shipment inspection and logistics. Buyers may request pre-shipment testing and packaging inspection. Delivery is arranged under FOB or CIF terms with the required documentation.

Use Case: 15-Year Industrial Monitoring Integration in the United Kingdom

Field evidence demonstrates how OEM cable capability translates into system performance. Shenghua Cable supplied cable for a medium-scale industrial system integration project in the United Kingdom, involving multiple equipment monitoring and data acquisition systems. The project duration was 15 years.

The product was used by a world-leading provider of predictive maintenance and intelligent diagnostic solutions for industrial machinery. It was applied in industrial monitoring systems, power signal transmission, and control circuit connectivity. The key technical highlights of the product include an ultra-small conductor size with high-voltage insulation capability, LSZH low-smoke zero-halogen flame-retardant construction, and excellent signal stability in high-density wiring.

Results from the application include improved overall system stability and safety, ensured continuous operation of critical monitoring equipment in harsh environments, and significantly reduced risk impact under fire and extreme conditions.
