Our Mission

Built on One Question

For thirty years, one question has driven everything we build:

Does it make the grid more reliable, more durable, and more economical over its full life?

If the answer is yes, we build it. If not, we don't.

That discipline — applied to every product, every partnership, every decision — is why utilities and OEMs across 100+ countries trust Shemar. And why we're here now, built for what the American grid needs next.

Core Values

What We Believe

You only earn value by creating it.

Not by capturing it. Not by claiming it. By building something that genuinely solves a real problem — for the customer, for the grid, for the people who depend on it. That belief has driven every technical decision at Shemar since day one, and it has never changed.

Root-Cause First

We only pursue problems the industry hasn't genuinely solved — not workarounds, not incremental tweaks, but root-cause materials innovation.

Performance Earns Trust

Global OEMs recognized Shemar through field results, not marketing. Every relationship we build is founded on demonstrated, measurable performance.

Beneficial to Humanity

We choose what is beneficial to the industry and society over what is merely expedient. That's the only kind of company we know how to be.

When people who share a conviction work together, they build things others can't. That shared conviction is our competitive moat — and it's what we're bringing to the American grid.

Our Journey

30 Years of Innovation & Recognition

From a $40K startup to a globally recognized grid technology company

1996 Founding

Company Founded

Founded by Ma Bin with $40K and one conviction: root-cause problem solving through materials innovation, while the global power industry manages seal failures as an operational inevitability.

1998 Innovation

Sealing Breakthrough

Reversed decades of conventional oil-resistant material approaches, demonstrating that solving root material challenges could eliminate chronic equipment failures.

1999 Innovation

Began Composite Station Post R&D

Pioneered high-temperature vulcanized silicone rubber insulators to address century-long porcelain failures: flashovers, fractures, and contamination that had never been fully solved.

2001 Market

Building Seal Market

Supplying ABB, Siemens, and GE — proving global OEMs recognized solutions through performance, not marketing.

2004 Recognition

International Validation by Global OEMs

Composite insulators adopted by ABB, GE, Siemens, representing 95%+ of global electrical equipment manufacturers. Technology officially recognized as filling an international gap (CMIC No. 010).

2005 Recognition

International Recognition from INMR

Dr. Torre, Chairman of the IEC Insulator Committee, visited Shemar and published an article in the industry's leading publication INMR, acknowledging Shemar's advanced technology and manufacturing capabilities.

2008 Innovation

Long-Life Transmission Line Composite Insulators

Shemar developed line composite insulators meeting full-lifecycle requirements under extreme conditions.

2010 Innovation

World's First Composite Transmission Tower Crossarm

Shemar developed the world's first composite crossarm for transmission towers — an international debut that redefined structural possibilities for the grid.

2013 Innovation

Development of Wrapped Auxiliary Sheds

Enhanced pollution performance with internationally leading composite technology.

2017 Innovation

Distribution Network Composite Crossarm Launch

Significantly improved lightning protection and prevented trip-offs in distribution lines.

2018 Recognition

Distribution Crossarm Recognized Internationally

Addressing global distribution challenges: lightning strikes, bird damage, and contamination-related failures — recognized as an industry-leading solution.

2019 Market

IPO on Shanghai Stock Exchange (603530)

18-month process completed with zero complaints; company declined real estate diversification and capital shortcuts to stay focused on grid technology.

2020 Recognition

400+ Patents & Global Reach

Patents in U.S., EU, Japan, South Korea, India, and Russia; products deployed in 100+ countries as composite insulation adoption accelerates worldwide.

2020+ Standards

Leading IEEE Standards Formulation

Authored IEEE P2833, P3196, and CEIS standards, transitioning from participant to industry shaper for composite insulation best practices.

2023 Market

U.S. Subsidiary Established in Memphis, TN

Joe Durante appointed CEO for North America & APAC; U.S. grid facing extreme stress: aging infrastructure, surging demand, and extreme weather events.

~2024 Market

North America Market Entry & Presence

NEMA membership; DISTRIBUTECH and IEEE trade show presence; building local commercial and technical teams while transmission buildout lags behind projected need (~900 miles built vs. ~5,000 miles/year).

2025–26 Expansion

Project Sunrise — Manufacturing Expansion (Cleveland County, NC)

Shemar USA scaling operations under new leadership; aligned with NERC 2025 LTRA forecast: 13 of 23 assessment areas at elevated/high risk, 224 GW summer peak demand growth, and $1.4T+ projected capital needs through 2030.

2026→ Vision

Materials-Driven Grid Innovation Partner for U.S. Utilities

Positioned to provide root-cause solutions for external insulation, lifecycle-optimized materials, and decades-long partnership thinking — precisely what the American grid needs after 30 years of development.
