Gutai to Exhibit UL-Approved Cable Glands and Solar MC4 Connectors at 140th Canton Fair

GUANGZHOU, China – September 9, 2026

Zhejiang Gutai Connector Co., Ltd. (Gutai), a professional manufacturer of wire and cable connectors, will present its certified waterproof electrical connector accessories at the 140th Canton Fair. International buyers are invited to visit Booth 15.2E37-38 to inspect the company’s UL-approved Nylon PA66 cable glands, solar MC4 connector series, and the factory-quality evidence behind those products.

Gutai said its Canton Fair participation will focus on one question that procurement teams increasingly ask: how can a buyer verify that a waterproof electrical connector accessory supplier can deliver consistent quality in volume? The company’s response at the booth will combine factory background, product parameters, material specifications and certification status.

Global demand for cable glands and related waterproof electrical connector accessories remains driven by industrial automation, new energy installations and infrastructure projects. In 2025, industry estimates placed the cable glands market at approximately USD 2.16–2.25 billion, with Asia Pacific representing an estimated 38–42% of global revenue. As these figures suggest, buyers are evaluating a larger pool of suppliers, making verifiable production evidence more important than ever.

Factory Evidence Behind the Products

Gutai operates a 5,000 m² manufacturing facility in Yueqing, Wenzhou, Zhejiang, China. The plant employs approximately 80 people and has an annual output capacity of 10,000,000 units. According to the company, about 80% of its production is exported to the Middle East, Southeast Asia, India, Pakistan, the EU, the United Kingdom and the USA.

The company states that it adheres to ISO 9001 international quality management system standards. For the cable gland lines on display, core products have passed CE, RoHS and REACH compliance checks and have been tested to IP68 ingress protection levels. These designations are frequently listed by buyers as baseline requirements for outdoor and industrial applications.

Material evidence is a key part of the display. Gutai uses UL-approved Nylon PA66 for the main structural parts of its plastic cable glands (components A/C/E/F). Nylon PA66 is specified for its mechanical strength and anti-aging behavior in electrical installation environments. Sealing parts (components B/D) are made from NBR nitrile butadiene rubber, providing the compression and oil resistance needed to maintain a seal around cables.

The company also documents operating limits, a factor that matters when matching a cable gland to an application. For its metric and PG plastic cable glands, static temperature range is -40°C to 100°C, with an instantaneous peak up to 120°C. In dynamic use the range is -20°C to 80°C, with an instantaneous peak up to 100°C. These figures help a designer judge whether a gland can survive the thermal environment of a motor, inverter or panel enclosure.

Cable Glands on Display: Metric and PG Series

At Booth 15.2E37-38, Gutai will exhibit a broad range of plastic cable glands, including both Metric and PG thread configurations. The products belong to the plastic cable gland, nylon cable gland, PG cable gland and metric cable gland categories.

The metric cable gland series covers thread sizes from M12 to M63. Cable clamping range is 3–45 mm, thread outer diameter is 12–63 mm, and thread length is 9–21 mm. The PG series spans PG7 to PG48, with cable range 3–45 mm, thread outer diameter 12.5–59.3 mm and thread length 9–21 mm. Having both systems allows distributors and OEM engineers to source for customers using different regional wiring standards.

Standard colors are black (RAL9005), light grey (RAL7035) and silver (RAL7001). Custom colors are available upon request for buyers who need visual matching or brand differentiation.

Gutai positions these cable glands for the new energy sector, industrial automation, construction and infrastructure, and marine engineering and shipbuilding. The IP68 rating indicates protection against continuous immersion under defined conditions, which is useful in outdoor cabinets, machine tools, LED lighting, marine gear and other wet environments.

Solar MC4 Connector Series

For PV and energy storage buyers, Gutai will show its solar MC4 connector family, including 1000V and 1500V versions as well as Y-type and T-type branch connectors. These connectors are designed for DC power connection in photovoltaic energy storage, lithium energy storage systems, new energy vehicles, AGV and industrial automation equipment, outdoor portable power stations, marine equipment, communication base stations and engineering machinery.

The 1000V MC4 connector series has a rated voltage of 1000V DC and rated current up to 30A for 2.5mm², 4mm² and 6mm² conductors, and up to 45A for 4mm² and 6mm² conductors. Test voltage is 6kV (50Hz, 1 min). Ambient temperature range is -40°C to +85°C under IEC and -40°F to +194°F under UL notation. Protection class in mated condition is IP67; when unmated, the touch protection rating is IP2X.

Electrical performance is supported by a connector contact resistance of no more than 0.5mΩ. Terminals are available in tin-plated copper or silver-plated copper, while the insulation housing is made from PC/PPO. The housing has a UL94 V-0 flammability rating, and the connector meets corrosion test class IEC 60068-2-52. The snap-in locking system allows quick field assembly, and metal plug options include Φ2.5mm, Φ4mm and Φ6mm.

These technical details are the product-level evidence that solar distributors and EPC contractors need when comparing connector suppliers, because array reliability depends on consistent contacts, housing insulation and sealing in outdoor conditions. In the global solar PV connector segment, MC4-style connectors hold an estimated 68% market share, according to Global Market Insights, underlining their importance in PV system design.

OEM/ODM and Customization Support

Many visitors to Canton Fair arrive with private-label plans or custom interface requirements. Gutai confirms that OEM projects are accepted. The company’s in-house engineering team currently includes 10 engineers, according to its company profile, and the factory can adapt standard products around custom colors and application-specific dimensions. This matters for buyers that want to consolidate sourcing without giving up flexibility.

A general boundary should be kept in mind: a cable gland protects only when the selected thread size and cable range match the cable and enclosure. A gland specified for one cable diameter cannot guarantee IP protection if used outside its clamped range. Gutai’s technical staff at the booth will help buyers identify the correct metric or PG gland for their cable diameter and panel opening.

Market Context and Certification Checks

The waterproof electrical connector accessories category is expanding with the growth of energy storage, solar PV and smart infrastructure. For cable glands, Asia Pacific is currently the largest regional market, and China is a major manufacturing base. Buyers sourcing from China often seek both cost competitiveness and documentation. Standard references in the sector include IEC 62444, which governs construction and performance requirements for cable glands for electrical installations, and IEC 60529 IP ratings for ingress protection. While not every product in a showroom is certified to every standard, buyers should ask the supplier to map which certification applies to which model.

Gutai states that its core cable gland products have passed CE, RoHS, REACH and IP68 testing; its Nylon PA66 parts are UL-approved, and its eco-friendly cable gland options are part of the same product family. Buyers are advised to request material certificates and test reports before finalizing specifications.
