Abstract: We study the network of Type-I cosmic strings using the field-theoretic numerical simulations in the Abelian-Higgs model. For Type-I strings, the gauge field plays an important role, and thus we find that the correlation length of the strings is strongly dependent upon the parameter $\ensuremath{\beta}$, the ratio between the masses of the scalar field and the gauge field, namely, $\ensuremath{\beta}={m}_{\ensuremath{\varphi}}^{2}/{m}_{A}^{2}$. In particular, if we take the cosmic expansion into account, the network becomes densest in the comoving box for a specific value of $\ensuremath{\beta}$ for $\ensuremath{\beta}<1$.
