Connecting the Circuit | One Woman’s Journey to Rewire the HV Jointing Industry

In an industry where women in High Voltage Engineering careers is rare, Francesca Distefano is rewiring the possibilities for what it means to be a leader in this male-dominated workplace.

With several years major projects experience and proven competency for the installation of market-leading brands including Pfisterer Connex, Nexans Euromold and NkT, Fran is excelling in her field and hopefully inspiring more women to write their own future and likewise thrive in the electrical power industry.

Francesca’s work powers our world; employed on critical infrastructure projects from data centres to digitise our economy and offshore wind farms that power our planets renewable energy future towards the global goal of Net Zero 2050.

Her personal journey, fuelled by resilience and the support of allies, highlights both the challenges women still face in the industry and the immense opportunities ahead.

Q&A WITH FRAN

HV Jointer | 66kV GWO’s | Gold Card Electrician | SSTS | 18th Edition

Jointing LV HV Cables UK & International Projects | Onshore & Offshore

Q: Fran, you’ve carved out an impressive career in the traditionally male-dominated role of HV Jointer. What inspired you to pursue this path, and how did you overcome challenges as a woman in the industry?

Fran: My journey began with the support of my family, especially my Dad, who’s a carpenter. He encouraged me to break away from traditional norms and pursue what made me happy. When I started I faced scepticism—some wrongly assumed I couldn’t handle the job as Jointer simply because of my gender.

But I focused on proving my skills through hard work, dedication and investment in training. Being physically fit and confident in my abilities helped me earn respect. Surrounding myself with supportive colleagues, like mentors Steve and Paul, and my boyfriend Ian, who brought me into HV, made all the difference.

Q: What aspects of your work bring you the most satisfaction?

Fran: The tangible impact of my work is incredibly rewarding. Whether it’s helping power hospitals, schools or data centres, knowing I’m contributing to essential infrastructure is fulfilling. I take pride in delivering high-quality work, and when others admire the results, it’s a great feeling.

Q: You’ve highlighted the importance of mentorship. How did these relationships shape your career?

Fran: Mentors like Steve, Paul, and Ian were pivotal. They taught me the ropes, stood by me during tough times, and helped me grow into the professional I am today. Their belief in me gave me the confidence to push forward, even when I doubted myself.

Q: What are the biggest challenges women still face in the industry today?

Fran: The lack of facilities, like female changing rooms and toilets, is a glaring issue. Many sites aren’t designed with women in mind, which adds unnecessary stress. There’s also the constant feeling of being “watched” or underestimated. But I’m optimistic—more women joining the field will drive change and companies are starting to adapt.

Q: As an HV Jointer which tools are indispensable to your work?

Fran: The Ripley US15 and US02 are my go-to Jointing Tools – the professionally engineered tools make stripping outer sheaths and cable semi-cons effortless, ensuring clean, precise work. These cable preparation tools have revolutionised efficiency especially in highly critical projects including offshore wind power and renewable energy.

Q: What advice would you give to women considering a career in HV Cable Jointing?

Fran: Don’t let fear hold you back. Yes, it’s intimidating at first, but the opportunities are endless—from joining to management or testing. The industry needs skilled workers, and women bring unique perspectives. Stand your ground, prove your worth, and don’t let anyone deter you.

Q: How can we encourage more women to join this field?

Fran: Showcasing the job’s rewards—travel, financial stability, and the pride of creating something lasting—is key. Breaking stereotypes and highlighting trailblazers can inspire others. Companies should also improve on-site facilities and actively recruit women.

Q: Where do you see opportunities for women in HV engineering over the next decade?

Fran: With global projects booming, women can make their mark internationally. As pioneers, we can reshape perceptions and inspire the next generation. I’ve already seen positive changes, and I hope the trend continues—more inclusivity, better facilities, and a stronger female presence on sites.

Q: Any final words for aspiring women engineers?

Fran: Go for it 100%. This industry is tough but incredibly rewarding. Be the change you want to see, and remember—you belong here just as much as anyone else.
